IntentClient: post intents and submit solver bids

Reference for the @agentbank/sdk IntentClient — postIntent, submitBid, settleAuction, cancelIntent, getOpenIntents, getIntent, and getBid methods.

IntentClient wraps the IntentRouter contract. Access it via client.intent.

Methods

postIntent

Post a new deposit intent to the auction system.

const txHash = await client.intent.postIntent({
  asset: "0x...",
  amount: "10000",
  minApyBps: 500,
  maxDrawdownBps: 200,
  duration: 30 * 86400,
});

Parameters (PostIntentParams):

Field	Type	Description
asset	Address	Deposit token
amount	string	Human-readable deposit amount
minApyBps	number	Minimum APY in basis points
maxDrawdownBps	number	Max acceptable drawdown in bps
duration	number	Lock duration in seconds
decimals	number	Asset decimals (default 18)

Returns: Promise<Hash>

---

submitBid

Submit a solver bid on an open intent.

const txHash = await client.intent.submitBid({
  intentId: 42n,
  tierVault: "0xC44C061D257Af305dEAea2eD093E878a615d856d",
  promisedApy: 650,
  bondAmount: "1000",
});

Parameters (SubmitBidParams):

Field	Type	Description
intentId	bigint	The intent to bid on
tierVault	Address	Vault address the solver proposes
promisedApy	number	Promised APY in bps
bondAmount	string	Bond amount (human-readable)
decimals	number	Bond token decimals (default 18)

Returns: Promise<Hash>

---

settleAuction

Settle the auction for an intent (callable by anyone after the deadline).

await client.intent.settleAuction(42n);

Returns: Promise<Hash>

---

cancelIntent

Cancel an open intent before the deadline (intent creator only).

await client.intent.cancelIntent(42n);

Returns: Promise<Hash>

---

getOpenIntents

Fetch recent open intents by scanning backwards from the latest ID.

const intents = await client.intent.getOpenIntents(50);

For production use, query the The Graph subgraph instead of using this method — it scans the chain directly and can be slow for large intent counts.

Returns: Promise<IntentData[]>

---

getIntent / getBid

const intent = await client.intent.getIntent(42n);
// intent.status: IntentStatus enum (Open=0, Filled=1, Expired=2, Cancelled=3)

const bid = await client.intent.getBid(7n);
// bid.solver, bid.promisedApy, bid.bondPosted, etc.
