1Shot API Onchain Automation with Delegations

1Shot API lets you build non-custodial onchain automation workflows in the most poplar automation platforms (n8n, Make and IFTTT) using MetaMask smart wallets and delegations.

Description

1Shot API is an automation-focused and enterprise-grade account abstraction and transaction service for the Ethereum mainnet and L2 ecosystem (Binance and Avalanche supported as well). It provides a simple REST API to trigger state-changing smart contract transactions (as well as smart contract reads) on a target blockchain network with a single POST call. 1Shot API can also be used in a completely non-custodial fashion by using its account delegation features built on top of MetaMask smart accounts.

Delegations allow users to connect self-custodied wallet to the 1Shot API service while retaining control over their private keys. 1Shot API also provides a delegation storage endpoint which lets apps leverage 1Shot API as a MetaMask smart account relayer for users. Compatible delegations are retrieved automatically on-demand when the app triggers a transaction on behalf of the user.

The most unique aspect of 1Shot API is its verified integrations with n8n, Make and IFTTT. These integrations enable crypto-enthusasts and professionals to build noncustodial workflows in the most popular automation platforms and have onchain transactions executed on their behalf (including Monad testnet) when they are not online thanks to the tight integration with MetaMask smart accounts.

Note: 1Shot API lets users read filted smart contract events inside their n8n workflows. Event reads are powered by Envio's HyperRPC API, which results in very fast event reads in workflows that benifit from smart contract event data.

Progress During Hackathon

During the hackathon, we extended our n8n verified community node to allow for delegated batch transactions for MM smart accounts. Additionally, we extended our IFTTT integration to support delegated transactions. We also, added support for Monad testnet in n8n, Make and IFTTT and integrated Envio's HyperRPC API to allows smart contract event reads from withing n8n workflows.

Fundraising Status

The 1Shot API team is entirely bootstrapped and focused currently on organically growing its userbase. We are considering a fundraise in early 2026.
