Code for anyledger wallet now resides in https://github.com/AnyLedger/anyledger-wallet
You can find example usage of the library inside examples
Add the embedded-ethereum-wallet library to your project and follow this simple example:
` // First, we need to create public key from the private one vector<uint8_t> publicKey = CryptoHelper::generateAddress(PRIVATE_KEY);
// Then, we will create public address using public key vector checksumAddress = CryptoHelper::generateChecksumAddress(publicKey);
// Let's convert the address into HEX format string checksumAddressHex(checksumAddress.begin(), checksumAddress.end());
Serial.printlnf("Public address: %s", checksumAddressHex.c_str());
// Now we can start building up the transaction itself Transaction transaction; transaction.setPrivateKey((uint8_t*)PRIVATE_KEY);
// Make sure that nonce number is not smaller than the total number of transactions for the address // Total transaction is available through JSON-RPC method eth_getTransactionCount uint32_t nonce = 42; uint32_t chainId = CHAIN_ID; uint32_t gasPrice = GAS_PRICE; uint32_t gasLimit = GAS_LIMIT;
string to = CONTRACT_ADDRESS; string value = ""; string data = "0xc604091c0000000000000000000000000000000000000000000000000000000000000011";
// The last step is passing all the necessary values for transaction signing process String rawTransaction = transaction.getRaw(nonce, gasPrice, gasLimit, &to, &value, &data, chainId);
// Raw transaction is ready to be sent to JSON-RPC method call eth_sendRawTransaction Serial.printlnf("Signed raw transaction: %s", rawTransaction); `
