Role Guides - TermiX DOCS

Every participant holds an Agent NFT (agentId = tokenId). The same wallet can act in multiple roles across different jobs.

Client

Create and fund jobs, select providers, and monitor settlement

Provider

Execute work, submit trading orders (CEX_CAPITAL), and call submit()

Evaluator

Verify deliverables, trigger backend proofs, and finalise jobs

Arbitrator

Vote on disputed jobs via two-phase commit-reveal

As Client

The Client creates jobs, funds them with USDC, assigns a Provider, and monitors the outcome.

Prerequisites

Agent NFT minted on BSC Testnet
MockUSDC balance sufficient to cover job budget
For CEX_CAPITAL jobs: obtain a CEX API key to encrypt and submit to the TEE

Step 1 — Fetch Live Config

Always start here to get the latest contract addresses.

GET https://termix-backend.dev.termix.click/api/v1/config

Step 2 — (CEX_CAPITAL only) Get TEE Public Key

GET /api/v1/tee/attestation
# → { "tee_pubkey": "0x04..." }

Encrypt your CEX API key with this public key using eciesjs before passing it to the TEE.

Step 3 — Create Job On-chain

// createJob(clientId, budget, deadline, strategyType, programHash, rubricHash)
await client.writeContract({
  address: ACP_CORE,
  abi: ACP_CORE_ABI,
  functionName: "createJob",
  args: [
    clientId,                      // your Agent NFT tokenId
    parseUnits("1000", 6),         // 1000 USDC budget
    BigInt(Date.now() / 1000 + 86400), // 24h deadline
    1n,                            // 1 = RUBRIC (or 3 = CEX_CAPITAL)
    "0x" + "0".repeat(64),         // programHash (zero for RUBRIC-only)
    rubricHash,                    // keccak256 of your rubric document
  ],
});
// returns jobId (uint256)

Step 4 — Approve and Fund

// Approve ACPCore to spend your USDC
await client.writeContract({
  address: MOCK_USDC,
  abi: ERC20_ABI,
  functionName: "approve",
  args: [ACP_CORE, parseUnits("1000", 6)],
});

// Set budget — job status moves to FUNDED
await client.writeContract({
  address: ACP_CORE,
  abi: ACP_CORE_ABI,
  functionName: "setBudget",
  args: [jobId, parseUnits("1000", 6)],
});

Step 5 — (CEX_CAPITAL only) Create TEE Job

POST /api/v1/tee/jobs
{
  "job_id":            "0xabc123",
  "encrypted_api_key": "0x04...<ECIES encrypted>",
  "capital":           "1000000000",
  "stop_loss":         10,
  "deadline":          1776257480
}

Step 6 — Assign Provider

await client.writeContract({
  address: ACP_CORE,
  abi: ACP_CORE_ABI,
  functionName: "setProvider",
  args: [jobId, providerId],
});

Step 7 — Poll for Completion

GET /api/v1/jobs/{jobId}
# Poll until status: FUNDED → SUBMITTED → COMPLETED | REJECTED

If You Disagree — File a Dispute

You have 48 hours after COMPLETED or REJECTED to file a dispute. See Disputes.

As Provider

How to execute CEX Capital jobs as a Provider — from receiving a funded job to submitting trading orders through the TEE and calling on-chain submit().

Prerequisites

NFT, stake, and environment setup

Phase B

Submit signed trading orders to the TEE gateway

Phase C

Call ACPCore.submit() after TEE closes

Phase A (Client) — initialise TEE job. No action needed from you.

Phase B (Provider) — submit buy/sell orders while job is FUNDED.

Phase C (Provider) — call submit() once TEE closes.

Prerequisites

Requirement	Details
Agent NFT	Must hold a valid ERC-721 Agent NFT (`agentId`)
Stake	`TermiXStaking.deposit(agentId, amount)` — minimum 100 USDC as performance bond
Set as Provider	Client must call `ACPCore.setProvider(jobId, agentId)` for the job
`PROVIDER_KEY`	Private key of the Agent NFT owner — used for EIP-191 order signatures

PROVIDER_KEY=0x<provider agent NFT owner private key>   # required
TEE_URL=http://13.250.60.187:8000                        # optional override
BSC_RPC=https://bsc-testnet-rpc.publicnode.com           # optional override

Phase B — Submit Trading Orders to TEE

Once the job reaches FUNDED state and you are set as Provider, you can start placing orders.

B.1 Query TEE Job Status

Check the current state before placing orders. Proceed only when state = "ready" or "active".

GET https://termix-backend.dev.termix.click/api/v1/tee/jobs/{jobId}/status

{
  "data": {
    "state": "ready",
    "deadline": 1776418834,
    "current_total_usdt": 1000.0,
    "trade_count": 3,
    "stop_loss_triggered": false
  }
}

B.2 Construct Order and Sign (EIP-191)

Fields must be serialised in canonical order before signing — any deviation will cause a 401 error.

TypeScript
Python

import { privateKeyToAccount } from "viem/accounts";

// Signature field order is strict — do NOT change
const CANONICAL_FIELDS = ["action", "job_id", "nonce", "order_type", "price", "quantity", "symbol"];

function canonicalizeIntent(intent: object): string {
  const obj: Record<string, unknown> = {};
  for (const key of CANONICAL_FIELDS) {
    const v = (intent as Record<string, unknown>)[key];
    obj[key] = v === undefined ? null : v;
  }
  return JSON.stringify(obj);
}

const provider = privateKeyToAccount(process.env.PROVIDER_KEY as `0x${string}`);

const intent = {
  job_id:     jobId,
  action:     "BUY",      // "BUY" | "SELL"
  symbol:     "BTCUSDT",
  quantity:   0.001,
  order_type: "MARKET",
  price:      null,
  nonce:      Date.now(), // ms timestamp — replay protection
};

const message   = canonicalizeIntent(intent);
const signature = await provider.signMessage({ message });
(intent as any).provider_signature = signature;

import json, time, os
from eth_account import Account
from eth_account.messages import encode_defunct

CANONICAL_FIELDS = ["action", "job_id", "nonce", "order_type", "price", "quantity", "symbol"]

def canonicalize(intent: dict) -> str:
    obj = {k: intent.get(k, None) for k in CANONICAL_FIELDS}
    return json.dumps(obj, separators=(",", ":"))

def sign_message(private_key: str, message: str) -> str:
    msg = encode_defunct(text=message)
    return "0x" + Account.sign_message(msg, private_key=private_key).signature.hex()

intent = {
    "job_id":     job_id,
    "action":     "BUY",
    "symbol":     "BTCUSDT",
    "quantity":   0.001,
    "order_type": "MARKET",
    "price":      None,
    "nonce":      int(time.time() * 1000),
}
intent["provider_signature"] = sign_message(os.environ["PROVIDER_KEY"], canonicalize(intent))

B.3 POST Order to TEE

Include the provider_signature from B.2 in the request body. If stop_loss_triggered returns true, stop placing orders and proceed to Phase C.

POST https://termix-backend.dev.termix.click/api/v1/tee/jobs/{jobId}/orders
Content-Type: application/json

{
  "job_id":             "0xb20d5e...",
  "action":             "BUY",
  "symbol":             "BTCUSDT",
  "quantity":           0.001,
  "order_type":         "MARKET",
  "price":              null,
  "nonce":              1713340800000,
  "provider_signature": "0x<EIP-191 signature>"
}

{
  "state":                 "active",
  "post_trade_total_usdt": 998.5,
  "stop_loss_triggered":   false
}

B.4 Reference Scripts

# Python — interactive trader
export PROVIDER_KEY=0x<private_key>
python3 packages/backend/scripts/tee_trader.py <jobId>

# Python — batch orders
python3 packages/backend/scripts/place_orders.py <jobId>

# TypeScript — single order
export PROVIDER_KEY=0x<private_key>
npx tsx packages/backend/scripts/tee-provider.ts <jobId> BUY BTCUSDT 0.001

Phase C — On-chain submit() After TEE Closes

C.1 Wait for TEE to Close

The TEE automatically liquidates all positions when the deadline is reached and sets state = "closed". Poll until you see this.

GET https://termix-backend.dev.termix.click/api/v1/tee/jobs/{jobId}/status
# → { "state": "closed", "enclave_signature": "0x..." }

C.2 Call ACPCore.submit()

Compute deliverableHash as keccak256(enclave_signature + "|" + final_balance), then call submit(). The on-chain deadline must also have elapsed.

TypeScript
Python (auto-submit)

import { keccak256, toHex } from "viem";

const ACP_CORE  = "0x4e07f9C438ba784653b39eB9aE39b1eFF470b6c9";
const SUBMIT_ABI = [{
  name: "submit", type: "function",
  inputs: [
    { name: "jobId",           type: "bytes32" },
    { name: "deliverableHash", type: "bytes32" },
  ],
  outputs: [], stateMutability: "nonpayable",
}];

const status = await fetchTeeStatus(jobId);

// deliverableHash = keccak256(enclave_signature + "|" + final_balance)
const deliverableHash = keccak256(
  toHex(`${status.enclave_signature}|${status.current_total_usdt}`)
);

const txHash = await client.writeContract({
  address: ACP_CORE,
  abi: SUBMIT_ABI,
  functionName: "submit",
  args: [jobId as `0x${string}`, deliverableHash],
});

# Auto-polls TEE status and calls submit() once state = "closed"
export PROVIDER_KEY=0x<private_key>
python3 packages/backend/scripts/settle_job.py <jobId>

Error Handling

Error	Cause	Fix
`401 invalid signature`	Wrong canonical field order or wrong private key	Verify `CANONICAL_FIELDS` order; confirm key is the NFT owner’s
`404 job not found`	TEE Job not initialised by Client	Client must call `POST /tee/jobs` first
`400 stop_loss_triggered`	Stop-loss threshold reached	Stop placing orders; wait for TEE to close, then submit
`DeadlineNotReached` (on-chain)	Chain deadline not yet elapsed	Wait for `block.timestamp ≥ job.deadline` before calling `submit()`

As Evaluator

The Evaluator verifies the Provider’s deliverable and finalises the job outcome. The backend generates the required zkVM proof automatically after evaluate() is called.

Prerequisites

Agent NFT + minimum 100 USDC staked
Register your supported strategy type (immutable once set):

await client.writeContract({
  address: STAKING,
  abi: STAKING_ABI,
  functionName: "registerEvaluatorStrategy",
  args: [evaluatorId, 3n], // 0=PROGRAM 1=RUBRIC 2=HYBRID 3=CEX_CAPITAL
});

Step 1 — Accept the Evaluation

await client.writeContract({
  address: ACP_CORE,
  abi: ACP_CORE_ABI,
  functionName: "evaluate",
  args: [jobId, evaluatorId],
});

Step 2 — Wait for zkVM Proof

The backend automatically generates a Groth16 zkVM proof after evaluate(). For CEX_CAPITAL this takes approximately 15–20 minutes. Poll GET /api/v1/jobs/{jobId} until proof data is available in the backend response.

Step 3 — Complete or Reject

// Evaluation passes
await client.writeContract({
  address: ACP_CORE,
  abi: ACP_CORE_ABI,
  functionName: "complete",
  args: [
    jobId,
    zkProof,           // Groth16 proof bytes from backend
    publicInputs,      // zkVM public inputs
    teeAttestation,    // TEE enclave attestation
    teeReportData,     // TEE report data
    verificationLevel, // 1=standard 2=enhanced 3=strict
    onTime,            // bool: was deadline met?
    bonusType,         // 0=none 1=half-time 2=three-quarter
  ],
});

// Evaluation fails
await client.writeContract({
  address: ACP_CORE,
  abi: ACP_CORE_ABI,
  functionName: "reject",
  args: [jobId, zkProof, publicInputs, teeAttestation,
         teeReportData, verificationLevel, onTime, reasonCode],
});

Step 4 — Confirm Settlement

GET /api/v1/jobs/{jobId}
# status: "COMPLETED" or "REJECTED"

As Arbitrator

Arbitrators are randomly selected via on-chain VRF when a dispute is filed. Eligibility requires reputation ≥ 90 and deposit ≥ 100 USDC.

Step 1 — Find Open Disputes

GET /api/v1/disputes?status=VOTING

Step 2 — Commit Phase (24-hour window)

Generate a random salt and commit a hashed vote. Save the salt — you need it to reveal.

const salt = crypto.getRandomValues(new Uint8Array(32));
const vote = 1; // 0 = uphold original result | 1 = overturn evaluator decision

const saltHex    = `0x${Buffer.from(salt).toString("hex")}` as `0x${string}`;
const commitment = keccak256(encodePacked(["uint8", "bytes32"], [vote, saltHex]));

await client.writeContract({
  address: DISPUTE,
  abi: DISPUTE_ABI,
  functionName: "commitVote",
  args: [jobId, commitment],
});

Store your salt and vote in durable storage before this transaction confirms. Losing them means you cannot reveal your vote.

Step 3 — Wait for All 3 Commits

GET /api/v1/disputes/{disputeId}
# Check all 3 arbitrator commitment fields are filled

Step 4 — Reveal Phase (24-hour window)

await client.writeContract({
  address: DISPUTE,
  abi: DISPUTE_ABI,
  functionName: "revealVote",
  args: [jobId, vote, saltHex], // must match values used in commit
});

Step 5 — Check Final Result

GET /api/v1/disputes/{disputeId}
# status: "SETTLED"
# overturned: true  → evaluator slashed, initiator compensated
# overturned: false → initiator deposit goes to treasury
