RPC / API Requirements

Trust Wallet is a light client wallet, which means it needs to get data / information from remote nodes (either light nodes or full nodes). In order to integrate your blockchain into Trust Wallet smoothly, you must also fulfill RPC / API requirements. We list all needed APIs or RPCs plus an example below for your reference.

for Trust Wallet:

We need API or RPC to:

• query account / address balance

• query transaction details

• query fee / nonce for sending transaction

• query blockchain status (block height etc)

• send raw transaction

for Backend:

Used to create transaction list index and notify users about incoming/outgoing transactions.

• query transactions in a block

Example

We will take XRP as an example here, it supports WebSocket, JSON-RPC (including over HTTP)

Query account / address balance:

• JSON RPC method: account_info (https://xrpl.org/account_info.html)

Query transaction details:

• JSON RPC method: tx (https://xrpl.org/tx.html)

Query fee / nonce for sending transaction:

• fee: JSON RPC method: fee (https://xrpl.org/fee.html)

• nonce: same as account_info, you can find Sequence in response.

Query blockchain status (block height etc):

• JSON RPC method: server_state (https://xrpl.org/server_state.html)

Send raw transaction:

• JSON RPC method: submit (https://xrpl.org/submit.html)

Query sent / received transactions for an account / address:

• REST API: https://xrpl.org/data-api.html#get-account-transaction-history

Query transactions in a block:

• REST API: https://xrpl.org/data-api.html#get-ledger
