Circle Products & Developer Toolings

USDC bridging to and from Pharos (mainnet and testnet) is now available via CCTP v2.

`@circle-fin/bridge-kit@1.9.0` — Pharos bridging support

`@circle-fin/provider-cctp-v2@1.7.0` — Pharos route added

`@circle-fin/adapter-viem-v2@1.9.0` — Pharos chain definitions

`@circle-fin/adapter-ethers-v6@1.6.6`, `@circle-fin/adapter-solana@1.5.6`, `@circle-fin/adapter-solana-kit@1.4.6` — Chain registry updated to include Pharos

`@circle-fin/bridge-kit@1.9.0`, `@circle-fin/provider-cctp-v2@1.7.0` — Bridge errors now expose a machine-readable errorCategory so apps can distinguish user rejections, wallet capability errors, and offchain vs onchain failures without string-matching

`@circle-fin/app-kit@1.4.2` — Fix kit.send() and kit.estimateSend() when sending from a Circle Wallet (you can now pass the wallet's address in from.address and the transfer will go through)

`@circle-fin/adapter-circle-wallets@1.2.8` — Circle Wallets operations now fall back to a local RPC when the Circle-hosted RPC cannot service the request, instead of failing

`@circle-fin/swap-kit@1.1.1`, `@circle-fin/provider-stablecoin-service-swap@1.1.1`, `@circle-fin/app-kit@1.4.2` — You can now reference cirBTC by its symbol when looking up tokens on Arc Testnet

`@circle-fin/bridge-kit@1.9.0`, `@circle-fin/swap-kit@1.1.1`, `@circle-fin/app-kit@1.4.2`, `@circle-fin/unified-balance-kit@1.0.2` — Sei (mainnet and testnet) chain.blockExplorers now point to the current explorers, so derived tx/address links resolve correctly

👀 cirBTC swaps are live on Arc Testnet — plus Pharos bridging and more.
