Create Bitcoin Anchor

Create Bitcoin Anchor

Prerequisites

1. The blockchain nodes much start defid with -spv enabled. If test on testnet, also need to enable -spv_testnet option. If test on regtest, then need to enable -fakespv.

2. If create anchor on bitcoin mainnet, then need to run a bitcoin node. If create anchor on bitcoin testnet, then need to run a bitcoin testnet node.

Create Anchor

The anchor is created with API command spv_createanchor. The first and second parameters are compulsary. An example on regtest

./defi-cli -regtest -rpcport=19554 spv_createanchor "[{\"txid\":\"528e61b53dcf04448693247866198ed0cf6488c42eb4f493f25da251f0a3af59\",\"vout\":3,\"amount\":10000,\"privkey\":\"your_private_key\"}]" mswsMVsyGMj1FzDMbbxw2QW3KvQAv2FKiy true 5000

Example on testnet:

./src/defi-cli -testnet spv_createanchor "[{\"txid\":\"528e61b53dcf04448693247866198ed0cf6488c42eb4f493f25da251f0a3af59\",\"vout\":3,\"amount\":106870,\"privkey\":\"your_private_key\"}]" 7AJwxLqAcN1zbkA8m33c5wFy8EGkzRghVX true 5000
