Thirdweb Account Abstraction Support

Purpose: Define the repo's concrete Thirdweb execution policy for ERC-4337, EIP-7702, gas sponsorship, and x402 across the chains relevant to GRU and Chain 138.

Machine-readable source: ../../config/thirdweb-account-abstraction-support.json

Verifier: ../../scripts/verify/check-thirdweb-account-abstraction-support.sh

Bottom line

The repo now treats Thirdweb account abstraction as a dual-mode surface:

  • ERC-4337 is the required compatibility baseline
  • EIP-7702 is the preferred execution mode where the chain and Thirdweb stack support it
  • x402 remains a 7702-specific settlement rail, not a generic 4337 fallback

For Chain 138 specifically:

  • ERC-4337 remains the current default execution mode in the policy matrix
  • EIP-7702 is tracked as supported target capability
  • x402 is enabled only through the GRU V2 USD payment tokens that expose ERC-2612 and ERC-3009

Chain 138 payment tokens

The Chain 138 x402-compatible payment tokens are:

  • cUSDT V2 — 0x9FBfab33882Efe0038DAa608185718b772EE5660
  • cUSDC V2 — 0x219522c60e83dEe01FC5b0329d6fA8fD84b9D13d

These contracts are live and expose:

  • permit / ERC-2612
  • transferWithAuthorization
  • receiveWithAuthorization
  • ERC-5267 domain introspection through the V2 token base

Verify

Run:

bash scripts/verify/check-thirdweb-account-abstraction-support.sh

Optional JSON output:

bash scripts/verify/check-thirdweb-account-abstraction-support.sh --json

This verifies:

  • dual-mode account abstraction is enabled in the matrix
  • Chain 138 explicitly lists both ERC-4337 and EIP-7702
  • Chain 138 keeps ERC-4337 as the current default until full 7702 confirmation
  • Chain 138 x402 stays pinned to eip7702
  • at least one Chain 138 payment token is listed as x402-compatible
  • Ethereum Mainnet is also represented as dual-mode
