# 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.

## 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
|
|
bash scripts/verify/check-thirdweb-account-abstraction-support.sh
|
|
```
|
|
|
|
Optional JSON output:
|
|
|
|
```bash
|
|
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
