chore(sdks): release UR v2.1.2 and v2.2.0 addresses

[claude]

Requested by Daniel Daniil · Slack thread

Description

Before: two feature PRs landed on main without a changeset, so neither shipped. #736 (feat(universal-router-sdk): add Universal Router v2.1.2 addresses, 91607ae) added the UniversalRouterVersion.V2_1_2 / URVersion.V2_1_2 enum member and the v2.1.2 router config for 24 chains. #738 (feat(universal-router-sdk): update Universal Router v2.2.0 addresses, 5cdddb0) repointed the v2.2.0 config on Ethereum mainnet, Ethereum Sepolia and Ink, and dropped Ink's V2_1_1 alias. With .changeset/ empty of entries, the Release workflow had nothing pending, opened no Version Packages PR, and published nothing — npm still serves @uniswap/universal-router-sdk@5.11.5 and @uniswap/v4-sdk@2.3.3 (both 2026-09-01), so neither the v2.1.2 addresses nor the corrected v2.2.0 addresses are available to downstream repos.

After: merging this single PR publishes directly — no intermediate Version Packages PR. The versioning step has already been run on this branch, so there are no pending .changeset/*.md files left; per .github/workflows/semantic-release.yaml, that is exactly the condition under which changesets/action takes the publish path (bun run g:release) rather than the version path. One merge to main releases:

package	from	to
@uniswap/universal-router-sdk	5.11.5	5.12.0	minor (#736 + #738)
@uniswap/v4-sdk	2.3.3	2.4.0	minor (#736)
@uniswap/sdk-core	7.19.2	7.19.3	patch (#737)
@uniswap/router-sdk	2.11.4	2.11.5	dependent patch
@uniswap/liquidity-launcher-sdk	1.16.2	1.16.3	dependent patch
@uniswap/smart-wallet-sdk	2.8.3	2.8.4	dependent patch
@uniswap/uniswapx-sdk	3.1.1	3.1.2	dependent patch
@uniswap/v2-sdk	4.21.3	4.21.4	dependent patch
@uniswap/v3-sdk	3.31.3	3.31.4	dependent patch

This release also carries #737 (fix(sdk-core): update permissioned posm addresses for deliveryGasLimit redeploy, 358d9de), whose changeset was still pending on main when this branch was rebased onto it — anything unreleased on main ships with the next publish regardless, so changeset version consumes it here. That is the source of the @uniswap/sdk-core patch and the five dependent patch bumps below it; the two headline minors are unaffected, since the #736 minor outranks a cascaded patch.

How: two changeset entries were written — a minor for #736 (new public enum member on UniversalRouterVersion and URVersion, so both packages bump in lockstep; toV4URVersion resolves across them by string value) and a patch scoped to universal-router-sdk for #738 (address-only update, no new enum member, and no other package touched). bun run version-packages (i.e. changeset version) was then run locally against current main and its output committed, so the 5.12.0 changelog section records both PRs. The version fields and the CHANGELOG.md entries in this diff were generated by changeset version, not hand-edited — including the dependent patch bumps that updateInternalDependencies: "patch" produces. The changeset source files are consumed and deleted by that step, which is why they do not appear in the final tree. No SDK source or test files are touched by this PR.

Why minor for #736, patch for #738: this repo's precedent for adding a new UniversalRouterVersion member plus its addresses is minor — "Add UniversalRouterVersion V2_2_0 (Sepolia) with permissioned-pool support" shipped as universal-router-sdk 5.5.0 (from 5.4.0) and v4-sdk 2.2.0 (from 2.1.1) from one changeset. Address-only edits are patch — 5.11.2 ("Update the Ethereum Sepolia Universal Router 2.1.1 address…") and 5.5.1 ("Add mainnet UniversalRouterVersion V2_2_0 router config and update sepolia V2_2_0 address"). The #736 minor dominates for universal-router-sdk, giving 5.12.0.

How Has This Been Tested?

This PR adds no code; the source being released was reviewed and merged in #736, #738 and #737. Locally on this branch, after the rebase onto 358d9de and the re-run of version-packages:

• bun run g:check:deps:mismatch (the monorepo-integrity check) — pass
• bun run g:build — 12/12 tasks successful
• bun run g:lint — 12/12 tasks successful (includes prettier --check '**/*.json' over the bumped package.json files)
• @uniswap/sdk-core — 375 pass, 0 fail
• @uniswap/v4-sdk — 240 pass, 2 skip, 0 fail
• @uniswap/router-sdk — 372 pass, 0 fail
• @uniswap/liquidity-launcher-sdk — 255 pass, 0 fail
• @uniswap/smart-wallet-sdk — 43 pass, 0 fail
• @uniswap/v2-sdk — 103 pass, 0 fail
• @uniswap/v3-sdk — 338 pass, 2 skip, 0 fail
• @uniswap/uniswapx-sdk — unit 350 pass, 0 fail. Its test:integration suite does not start locally (HH8: Invalid value {"chainId":1,"forking":{"enabled":true}}) because the fork URL comes from a CI-only secret.
• @uniswap/universal-router-sdk — 526 pass, 1 fail. The single failure is test/uniswapTrades.test.ts, whose before all hook needs the mainnet fork RPC from FORK_URL (Error: could not detect network); that env var is not available locally. Its sibling unit suite test/utils/constants.test.ts — the one that covers the addresses being released — runs clean at 226 passing. CI has the fork URL and Foundry, so it exercises both.

Are there any breaking changes?

No version-policy breaking change: no package takes a major bump, and #736 is purely additive. One behavioral note carried over from #738 and now recorded in the 5.12.0 changelog: Ink (57073) no longer has a V2_1_1 entry. That entry had been an alias pointing at Ink's old v2.2.0 router rather than a real v2.1.1 deployment, so getUniversalRouterAddress(UniversalRouterVersion.V2_1_1, 57073) stops resolving; callers on Ink should use V2_1_2 or V2_2_0. That change is already on main — this PR only releases it.

(Optional) Feedback Focus

Worth a second pair of eyes on the intent to publish in one merge: this branch deliberately carries the versioning output so the Release workflow publishes on merge rather than opening a chore(sdks): Version Packages PR for a separate approval. Note that this also means #737's sdk-core patch publishes on the same merge. If you would rather keep the two-step review gate, say so and this can be reverted to a changeset-only PR.

Approved.

Releases the v2.1.2 (#736) and v2.2.0 (#738) Universal Router addresses by committing the changeset version output — minor bumps for universal-router-sdk (5.12.0) and v4-sdk (2.4.0), with dependent patches cascading to the workspace:* consumers plus the #737 sdk-core patch.

Assessment

The version math is the correct mechanical output of changeset version: a minor for the new UniversalRouterVersion.V2_1_2 enum member, dependent patches for every consumer of the bumped packages, and CHANGELOG headings that match each package.json. .changeset/ holds only config.json, so the merge takes the publish path rather than opening a Version Packages PR. The universal-router-sdk changelog now documents #738's v2.2.0 address repointing and the Ink V2_1_1 removal — including that getUniversalRouterAddress(V2_1_1, 57073) now throws.
