What is a back-end wallet?
Back-end wallets are api for blockchain wallets that run on the server side and enable automated transactions, token transfers, and contract interactions without the need for user intervention. They are essential for:
Automated casting operation
No gas trading relay
Batch operation
Server-side blockchain interaction
Engine back-end wallet API
thirdwebEngine provides a comprehensive set of endpoints for managing and leveraging back-end wallets. Let's break down what you can do:
1. Wallet lifecycle management
These endpoints handle the creation, import, update, and deletion of api for blockchain back-end wallets.
POST/ Back-end wallet/Create
→ Create a new wallet
POST/ Back-end wallet/Import
→ Import existing wallets
POST/ Back-end wallet/Update
→ Modify wallet Settings
Delete/back-end wallet /{walletAddress}
→ Safely remove your wallet
2. Asset operation
Handle everything related to the assets in your wallet. These endpoints provide visibility into wallet holdings and allow assets to be moved between addresses.
GET/ Back-end wallet /{chain}/{walletAddress}/ Get the balance
→ Check your wallet balance
POST/ Back-end wallet /{chain}/ Transfer
→ Move assets between wallets
POST/ Back-end wallet /{chain}/ withdrawal
→ Withdraw funds from your wallet
3. Transaction processing
Transaction processing is your interface to the blockchain itself. These endpoints allow you to perform actions on the blockchain, ranging from simple transfers to complex smart contract interactions. This group handles both single and batch transactions and has built-in simulation capabilities that can be tested before execution.
POST/ back-end wallet /{chain}/ Send transactions
→ Execute a single transaction
POST/ back-end wallet /{chain}/ Send transaction batches
→ Handle multiple operations
POST/ Back-end wallet/signature transactions
→ Sign without sending
POST/ Back-end wallet /{chain}/ Mock transaction
→ Pre-execution test
4. Sign the file
Signing operations handle all signing requirements, from basic messages to complex structured data. This group is essential for creating verifiable proofs and authorizing transactions without immediately having to broadcast them to the blockchain.
POST/ Back-end wallet/signature message
→ Sign any message
POST/ Back-end wallet/signature data type
→ Symbol Type data (EIP-712)
5. Transaction management
Transaction management provides visibility and control over the transaction pipeline. These endpoints help you track transaction status, manage random number sequences, and maintain a healthy transaction flow.
GET/ Back-end wallet /{chain}/{walletAddress}/ Get all transactions
→ View transaction history
GET/ Back-end wallet /{chain}/{walletAddress}/ get-nonce
→ Manage transaction sequences
POST/ Back-end wallet/Reset password
→ Handle random number conflicts
A reliable api for blockchain is critical to building robust web3 applications. thirdwebEngine's back-end wallet provides the foundation for secure, scalable blockchain operations. Whether you're building an NFT market, implementing gas-free trading, or managing complex token operations, these API endpoints give you the tools you need to succeed.
