Changelog

Sourced from agentwallet-sdk's changelog.

[6.2.0] — 2026-04-13

Added

• UptoBillingPolicy for x402 usage-based billing, with max authorization tracking, actual settlement recording, unused-capacity release, and wallet ledger deltas
• Test coverage for partial settlement, finalization, over-cap rejection, and multi-settlement flows

Changed

• Exported UptoBillingPolicy from the main SDK entrypoint
• Updated README examples and package metadata to position agentwallet-sdk as an x402 usage-based billing reference implementation
• Simplified PaymentRouter.isRailLive() boolean handling

---

[6.0.0] — 2026-03-21

Added

• TokenRegistry class — 80+ verified token addresses across 11 EVM chains + Solana
  • Pre-populated registries: USDC, USDT, DAI, WETH, WBTC, LINK, UNI, AAVE, CRV, MKR, SNX, COMP, LDO, ARB, OP, and more
  • Native gas token support (ETH, POL, AVAX, S) with isNative flag
  • addToken() for custom token imports
  • Per-chain registry exports: BASE_REGISTRY, ETHEREUM_REGISTRY, ARBITRUM_REGISTRY, etc.
• Multi-token EVM transfers: sendToken(), sendNative(), getTokenBalance(), getNativeBalance(), getBalances()
• Human-readable amount handling: toRaw(), toHuman(), formatBalance()
• Solana SPL token support (optional peer dependency @solana/web3.js):
  • SolanaWallet class with getSolBalance(), sendSol(), sendSplToken(), getSplTokenBalance()
• x402 multi-asset resolution — payments now accept any token the server requests, not just USDC

Changed

• x402 client updated to resolve assets via TokenRegistry (multi-asset support)
• Bumped version to 6.0.0

Backward Compatible

• All v5.x imports continue to work unchanged

[5.2.0] — 2026-03-16

Added

• Multi-chain x402 payments: Expanded from 1 chain (Base) to 10 mainnet chains — Ethereum, Arbitrum, Polygon, Optimism, Avalanche, Unichain, Linea, Sonic, World Chain
• Solana CCTP bridge: EVM↔Solana USDC bridging via Circle CCTP V2 (domain 5). Self-contained base58 encoder, no hard @​solana/web3.js dependency
• Multi-chain swap: Uniswap V3 support expanded to Arbitrum, Optimism, and Polygon (was Base-only)
• Chain config expansion: SupportedChain type and CHAIN_IDS map for all 11 chains
• Mainnet bridge proof: Verified Base→Arbitrum CCTP V2 transfer (0.50 USDC, tx 0xfedb...9129)

Fixed

• Critical: Solana CCTP V2 addresses — TokenMessenger and MessageTransmitter were using V1 program IDs. Updated to V2 (CCTPV2vPZJS2u2BB... and CCTPV2Sm4AdWt52...). Verified against Circle docs + circlefin/solana-cctp-contracts
• CCTP V2 depositForBurn signature — Updated from 4-param V1 to 7-param V2 (added destinationCaller, maxFee, minFinalityThreshold)
