Swap Assets using the Ravencoin Core
To swap assets using code on Ravencoin, you can use the createrawtransaction, fundrawtransaction, and signrawtransaction RPC commands from the Ravencoin daemon's RPC interface.
Here is an example of how you can use these commands in JavaScript to swap one asset for another:
const rp = require('request-promise');
const createTransaction = async (asset1, qty1, asset2, qty2) => { // Create an empty transaction const createTxOptions = { method: 'POST', uri: 'http://localhost:8766/', body: { jsonrpc: '1.0', id: 'curltest', method: 'createrawtransaction', params: [[], {}} }, json: true };
const createTxResponse = await rp(createTxOptions); const txHex = createTxResponse.result;
// Add inputs to the transaction const fundTxOptions = { method: 'POST', uri: 'http://localhost:8766/', body: { jsonrpc: '1.0', id: 'curltest', method: 'fundrawtransaction', params: [txHex, {'asset1': qty1, 'asset2': qty2}] }, json: true };
const fundTxResponse = await rp(fundTxOptions); const fundedTxHex = fundTxResponse.result.hex;
// Sign the transaction const signTxOptions = { method: 'POST', uri: 'http://localhost:8766/', body: { jsonrpc: '1.0', id: 'curltest', method: 'signrawtransaction', params: [fundedTxHex] }, json: true };
const signTxResponse = await rp(signTxOptions); const signedTxHex = signTxResponse.result.hex;
return signedTxHex; };
(async () => { const asset1 = ':'; const qty1 = ; const asset2 = ':'; const qty2 = ;
const signedTxHex = await createTransaction(asset1, qty1, asset2, qty2); console.log(signedTxHex);
// Send the signed transaction to the network const sendTxOptions = { method: 'POST', uri: 'http://localhost:8766/', body: { jsonrpc: '1.0', id: 'curltest', method: 'sendrawtransaction', params: [signedTxHex] }, json: true };
const sendTxResponse = await rp(sendTxOptions); console.log(sendTxResponse); })();
This code creates a raw transaction that swaps asset1
