# Batch transactions

WalletChan supports ERC-5792 call bundles and a user-assembled cross-dapp batch.
A batch can reduce prompts, preserve dependent call order, or execute
atomically when the account and network support it.

## Dapp batches

Supported provider and WalletConnect methods include:

* `wallet_getCapabilities`
* `wallet_sendCalls`
* `wallet_getCallsStatus`
* `wallet_showCallsStatus`

A one-call bundle uses the normal single-transaction review. Multi-call review
shows ordered calls, dapp attribution, simulation, approvals, decoded/raw data,
gas, and whether atomic execution is required.

You can expand calls, edit supported approval values, remove calls where the
request permits, or split a compatible batch. A dapp-required atomic bundle
cannot silently become sequential.

## Execution strategy

| Account | Batch behavior |
| --- | --- |
| Private key / seed | EIP-7702 + ERC-7821 atomic when compatible; otherwise sequential if allowed |
| Ledger | Not advertised for ERC-5792 batches |
| View-only | Unsupported |
| Safe | Creates a Safe proposal; bundle stays pending through real execution |
| Bankr | Atomic ERC-7821 on supported paths |

Bundle status records retain per-call results and transaction receipts.

## Cross-dapp batch

For compatible pending transaction requests on one account and chain, choose
**Add to batch**. The combined review groups calls by source site. You can
remove one source, reject its original request, reject all, or confirm once.

WalletChan pins the assembled batch to the original account/chain and fans the
final transaction hash/status back to each source. Bankr can use an atomic
plan; local private-key/seed accounts require a compatible EIP-7702 path.

## Partial sequential execution

Sequential batches can stop after an earlier call succeeds. Activity records
the completed and failed call indices. Check for remaining token approvals or
partially completed state before retrying.
