Summary

Maintenance sweep. viem 2.57.2 to 2.57.3 (exact pin and the matching override), part of the coupled viem/mppx set moving together across pay, node-commerce and the storefronts. 2.57.3 is patch fixes only; two touch our settle path: automatic relay fee-token selection now skips tokens without fee AMM liquidity (Tempo), and waitForTransactionReceipt no longer treats the awaited transaction as its own replacement when its receipt is briefly unavailable. Version 0.6.5, since viem ships in the package.

Worked with: Varun.

Not done: the esbuild ^0.28.1 override was re-tested by removing it and stays (without it a second esbuild 0.27.7 returns). Every other dependency is current; eslint 10 and TypeScript 7 stay held per the org holds registry (their lift conditions re-tested today, unmet). The incur patch is unchanged (incur not bumped).

Type of change

• Bug fix (no breaking change)
• New feature (no breaking change)
• Breaking change (existing callers must update)
• Docs, tests, or internal maintenance only

Public API

None.

Test plan

Ran locally: bun run lint, typecheck, knip, test (578 passed, 2 skipped), build. All green; a second bun install is a no-op. After release, a live settle on Base, Tempo and Solana against a storefront on the new versions.

Checklist

• Tests cover the new behavior, and the suite passes locally
• Lint, format, and type checks pass
• Docs and README examples updated if the public surface changed (no public surface change)
• No secrets, credentials, or personal data in the diff or the tests

Live settle for the coupled-set move (viem 2.57.3), both sides on the new versions: the published CLI 0.6.5 from npm, against the FullEnrich storefront deployed from its own viem 2.57.3 / hono 4.13.13 merge. Smoke wallet, mainnet, 2026-10-05.

Rail	Ungated (/company/lookup, $0.02)	Gated (/person/enrich/work-email, $0.07, KYC passport attached)
Base (x402)	200, settled	200, settled, result returned
Tempo (MPP)	200, settled	200, settled, result returned
Solana (MPP)	200, settled	200, settled, result returned

Balances moved by exactly the two prices on Base (2.070968 to 1.980968) and Solana (0.670000 to 0.580000), and on Tempo by the two prices plus the network fee (0.545118 to 0.454762), so each 200 is a real settlement rather than a cached response.
