Safe Transaction Service API Reference


The Safe Transaction Service API Reference is a collection of endpoints that allow to keep track of Safe transactions.
This service is available on multiple networks, at different endpoints.
Base URL: https://safe-transaction-blast.safe.global

Create Delegate


Adds a new Safe delegate with a custom label. Calls with same delegate but different label or signer will update the label or delegator if a different one is provided. To generate the signature, the following EIP712 data hash needs to be signed:

_23
{
_23
"types": {
_23
"EIP712Domain": [
_23
{"name": "name", "type": "string"},
_23
{"name": "version", "type": "string"},
_23
{"name": "chainId", "type": "uint256"},
_23
],
_23
"Delegate": [
_23
{"name": "delegateAddress", "type": "address"},
_23
{"name": "totp", "type": "uint256"},
_23
],
_23
},
_23
"primaryType": "Delegate",
_23
"domain": {
_23
"name": "Safe Transaction Service",
_23
"version": "1.0",
_23
"chainId": chain_id,
_23
},
_23
"message": {
_23
"delegateAddress": delegate_address,
_23
"totp": totp,
_23
},
_23
}


For the signature we use TOTP with T0=0 and Tx=3600. TOTP is calculated by taking the Unix UTC epoch time (no milliseconds) and dividing by 3600 (natural division, no decimals).

Delete Delegate


Removes every delegate/delegator pair found associated with a given delegate address. The signature is built the same way as for adding a delegate, but in this case the signer can be either the delegator (owner) or the delegate itself. Check POST /delegates/ to learn more.

Delete Queued Multisig Transaction


Removes the queued but not executed multi-signature transaction associated with the given Safe tansaction hash. Only the proposer or the delegate who proposed the transaction can delete it. If the transaction was proposed by a delegate, it must still be a valid delegate for the transaction proposer. An EOA is required to sign the following EIP-712 data:

_25
{
_25
"types": {
_25
"EIP712Domain": [
_25
{"name": "name", "type": "string"},
_25
{"name": "version", "type": "string"},
_25
{"name": "chainId", "type": "uint256"},
_25
{"name": "verifyingContract", "type": "address"},
_25
],
_25
"DeleteRequest": [
_25
{"name": "safeTxHash", "type": "bytes32"},
_25

},
_25
"message": {
_25
"safeTxHash": safe_tx_hash,
_25
"totp": totp,
_25

totp parameter is calculated with T0=0 and Tx=3600. totp is calculated by taking the Unix UTC epoch time (no milliseconds) and dividing by 3600 (natural division, no decimals)

List Transactions


Returns all the executed transactions for a given Safe address. The list has different structures depending on the transaction type:

- Multisig Transactions for a Safe. tx_type=MULTISIG_TRANSACTION.

- Module Transactions for a Safe. tx_type=MODULE_TRANSACTION

- Incoming Transfers of Ether/ERC20 Tokens/ERC721 Tokens. tx_type=ETHEREUM_TRANSACTION Ordering_fields: ["timestamp"] eg: -timestamp (default one) or timestamp

Note: This endpoint has a bug that will be fixed in next versions of the endpoint. Pagination is done using the Transaction Hash, and due to that the number of relevant transactions with the same Transaction Hash cannot be known beforehand. So if there are only 2 transactions with the same Transaction Hash, count of the endpoint will be 1 but there will be 2 transactions in the list.

Query Parameters
