Deployments

Testnet only. x207 has not been deployed to mainnet. Every account below is a NEAR testnet account.

Active circleCopy Anchor Link

The current circle is x207-v018.testnet (contract interface 0.0.18).

The token is a mock USDT contract on testnet, not real USDT or USDC. The redeploy that added the escrow limit max_escrow_ttl is transaction Bx2qeVrB9z8WTH2FXnHvxp5DztEpmuJRGPaQ3SwgzTXu.

Read it yourself, with no account and no key:

curl -s https://rpc.testnet.fastnear.com -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"query","params":{"request_type":"call_function","finality":"final","account_id":"x207-v018.testnet","method_name":"interface_version","args_base64":""}}'

The result holds the bytes of a JSON string; decode it to read 0.0.18. Other views are listed in Views.

What ran on 0.0.18Copy Anchor Link

All of these are testnet runs recorded in the repo, each with transaction hashes in the named file.

• A three-agent barter ring in epoch 184: one commit_bundle, 81 credit traded, 72 removed by clearing, 8 mock USDT moved. One operator signed for all three agents; only credit moved, no asset was delivered in that run. File: docs/demo-barter-cycle.md in the agents repo.
• A second barter ring, AG-055, in epoch 245 (circle agents-main), that delivered assets. Three agents each sold a mock NFT to the next one: alice to bob, a software licence NFT for 24 credit; bob to dan2, an event ticket NFT for 32 credit; dan2 to alice, a game item NFT for 25 credit. Each seller sent the NFT into contract escrow with nft_transfer_call. The buyer then called complete_escrow, which registered the voucher and sent the NFT to the buyer, and the NFT owners changed on chain. Gross 81, clearing removed 72, net 8 mock USDT moved (alice paid 1, dan2 paid 7, bob claimed 8). The epoch finalized with shortfall 0. Limits: the mock NFT contract is nft.x207-b1-aux.testnet; the operator set the prices, because the live appraiser valued the mock tokens at 0, 0 and 0.5 credit; there were three separate complete_escrow transactions, not one bundle; one operator played all three agents; testnet only, mock USDT. During this run the v018 owner registered the asset classes license:software-nft, ticket:event-nft and game:item-nft with set_asset_class. Transactions: complete_escrow GWF3npguAhQALgfAjb7evpeDhGYHdWzD1yLwm3yGrp9K, 4ajpqavyrhBqhd6uBTMzKVkEAN5XzEtY4RfLXVarA7tz, GmhhMhPjbMoucGJbCU9Qm7FaHXfkRCC1d6KdfeoXkvPz; submit_clearing 9MfU2iY9Lt4XXTdSnnwqGnP4DRmZHhFdjMPFbtNdkXn9; finalize_epoch FTwZq3emNoYXfAoYwgGLX9fnHZ8KBTiVqF3EMSXUkTrA. File: docs/demo-barter-ring-assets.md in the agents repo (source).
• A voucher over the payer's headroom refused with ERR_INSUFFICIENT_CREDIT (epoch 183), with the seller middleware in register-first and default mode (mock facilitators). File: docs/testnet-epochs/ct132-overspend-run.json in the contracts repo.
• Sale of a NEAR account through a locker (barter kinds 11 and 14): a delivery, a refused early delivery (ERR_ESCROW_EPOCH_WAIT), the old voucher key refused after rotation (ERR_BAD_SIGNATURE), the buyer's key accepted. Files: docs/testnet-p1-v018.json, docs/testnet-ct127-close.json, docs/testnet-ct131-rotation.json.
• The escrow limit max_escrow_ttl: a 24-hour grant locked, an 80-hour grant refused. File: docs/testnet-ct129-ttl-smoke.json.
• The first of these runs used the first 0.0.18 build, before max_escrow_ttl. cancel_expired_account_escrow on testnet is not covered by a transaction; it is covered in a sandbox test.

Earlier circlesCopy Anchor Link

Older circles stay on testnet. They are different builds of the same contract; each has its own account.

Epoch runs of the 0.0.13 circle, with transaction hashes, are in docs/testnet.md (a realistic epoch with partial clearing, five residuals and one default; a load test with all 15 x 14 = 210 edges) and contracts/docs/gas-and-cost.md.

The deployed builds of 0.0.14 and 0.0.15 were checked against the reproducible build of their tags on 2026-11-05 (source: CLAIMS.md).

Keeper accountCopy Anchor Link

A keeper sends close_epoch, commit_epoch and finalize_epoch. For the 0.0.18 circle it is a function-call key on x207-v013-aux.testnet. It is run by the x207 team and is not special: any account can call these methods.

Verify a deployed buildCopy Anchor Link

Rebuild the release in a pinned container and compare with the chain:

scripts/repro-build.sh <git-ref> <outdir>
scripts/verify-release.sh v0.0.18 x207-v018.testnet

The check compares the sha256 of the rebuilt wasm with the code hash the RPC returns for the account. It proves the deployed bytes equal the release at that tag. It does not prove the source is free of bugs. Details: contracts/docs/verify-release.md.

Not deployedCopy Anchor Link

• Mainnet: no circle, no deploy. Mainnet needs the owner's decision; the repo holds a checklist, not a deploy.
• Real NEAR Intents on testnet: Intents has no code on testnet. The mt_on_transfer and withdraw_intents_balance paths run on testnet against a mock. Against the real mainnet Intents wasm they run only in a near-sandbox test.
• Real USDT or USDC: every testnet circle uses the mock token.
