Tools for signing

In order to sign a transaction without actually dispatching it, one can use erdpy or erdwalletjs-cli.

Sign using erdpy (Command Line Interface)

Using a pem file:

$ erdpy tx new --nonce=41 --data="Hello, World" --gas-limit=70000 \
--receiver=erd1l453hd0gt5gzdp7czpuall8ggt2dcv5zwmfdf3sd3lguxseux2fsmsgldz \
--pem=aliceKey.pem --pem-index=0 --outfile=myTransaction.json

Using a JSON wallet key (and its password):

erdpy tx new --nonce=41 --data="Hello, World" --gas-limit=70000 \
--receiver=erd1l453hd0gt5gzdp7czpuall8ggt2dcv5zwmfdf3sd3lguxseux2fsmsgldz \
--keyfile=walletKeyOfAlice.json --passfile=passwordOfAlice.txt \
--outfile=myTransaction.json

In either case, the output file looks like this:

{
"tx": {
"nonce": 41,
"value": "0",
"receiver": "erd1l453hd0gt5gzdp7czpuall8ggt2dcv5zwmfdf3sd3lguxseux2fsmsgldz",
"sender": "erd1aedmqfsflx4rhwvs7v9z52e7eylkevz4w342jzuaa9ezy5unsc5qqy963v",
"gasPrice": 1000000000,
"gasLimit": 70000,
"data": "SGVsbG8sIFdvcmxk",
"chainID": "1596807148",
"version": 123,
"signature": "f432442ebfee6edf4518c10d006ab571d8ecbd6f2601995554c75d3402b424364908235d45449ba5dd28575e4a8129271020e4718cf8a4c6f44e22c0885ac40a"
},
"hash": "",
"data": "Hello, World"
}

Sign using erdwalletjs-cli

Given an unsigned transaction in a JSON file:

{
"nonce": 42,
"receiver": "erd1cux02zersde0l7hhklzhywcxk4u9n4py5tdxyx7vrvhnza2r4gmq4vw35r",
"value": "100000000000000000",
"gasPrice": 1000000000,
"gasLimit": 70000,
"data": "food for cats",
"chainID": "1",
"version": 1
}

You can sign it as follows:

$ erdwalletjs sign -i ./aliceToBob.json -o ./aliceToBobSigned.json \
-k walletKeyOfAlice.json -p passwordOfAlice.txt

The signed transaction looks like this:

{
"nonce": 42,
"value": "100000000000000000",
"receiver": "erd1cux02zersde0l7hhklzhywcxk4u9n4py5tdxyx7vrvhnza2r4gmq4vw35r",
"sender": "erd1ylzm22ngxl2tspgvwm0yth2myr6dx9avtx83zpxpu7rhxw4qltzs9tmjm9",
"gasPrice": 1000000000,
"gasLimit": 70000,
"data": "Zm9vZCBmb3IgY2F0cw==",
"chainID": "1",
"version": 1,
"signature": "5845301de8ca3a8576166fb3b7dd25124868ce54b07eec7022ae3ffd8d4629540dbb7d0ceed9455a259695e2665db614828728d0f9b0fb1cc46c07dd669d2f0e"
}
