Pool buyer demand
Each agent sends a quantity and a total cap. The round adds them into one order.
TypeScript SDK for agent markets on NEAR
Buyer agents pool demand, sellers bid in sealed rounds, and each buyer pays only its share. One round clears 90 GPU hours for 20 buyers.
20 of 20 payments final on NEAR testnet, each checked against RPC.
Every buyer’s share, from bid to receipt
Each buyer agent posts a quantity and a spend cap. The round clears, then the runner signs, journals and confirms every payment. Read the settlement guide

A round in 3 steps
Seal each seller agent’s bid
Sellers commit a SHA-256 hash, then reveal. A reveal that does not match is dropped.
TSseller.tssealed
const bid = { capacity: "90",
unitPrice: "4", salt };
const hash = await
commitBid(id, seller, bid);
round.submitCommitment(
seller, hash);
// after commitCloses
await round.revealBid(
seller, bid);Reveal matches the hash.
Pay each buyer agent’s share
Buyers sign a spend cap. The runner pays within it and resumes after a crash.

Who owns what
Your agents decide what to buy and what to charge. SwarmKit admits them to a round, keeps every bid sealed until the deadline, clears it by the published rule, records a transcript anyone can replay and pays each share on NEAR.
22 payments on NEAR testnet, with receipts
Two runs on 14 November 2026 from faucet-funded subaccounts. Every transfer links to its finalized transaction.

Does the GPU co-op spend real NEAR?
Only testnet NEAR. Prices are simulated dollars; pressing Settle pays your share on NEAR testnet at 0.0001 NEAR per dollar.
Does SwarmKit settle through NEAR Intents?
Yes. A SwarmKit round has settled on mainnet through intents.near: a signed NEP-413 transfer, preflighted, executed and reconciled by the SDK. See the transaction
Can I write my own allocation rule?
Yes. Give a mechanism a versioned id and a selectWinner or allocate function. Replay and audit use the same rule.
What if the process dies mid-payment?
The runner journals each signed transfer before sending it. On restart it checks the stored hash instead of signing again.
Do agents need a language model?
No. A strategy is an async function. Scripted ones replay from a seed; a model can sit behind the same function.
Run the SDK in this page
The panel imports the packaged near-swarmkit build. Each press runs one stage of a two-buyer, two-seller round with split fulfillment.
import { startSimulation, advanceSimulation,
replayRound } from "near-swarmkit";
let session = startSimulation(agents);
// one stage per press; persist between them
session = await advanceSimulation(session, agents);
const snapshot = await replayRound(session.transcript);- Demand
