btc router specials

btc token config ContractAddress item

ContractAddress is BTC or format of Currency

btc stands for native

btc chain and token config RouterContract item

RouterContract is the mpc address

btc public key to btc address

go run tokens/btc/tools/pubKeyToAddress/main.go -pubKey 0409373c48ead4253c79f0f2063139170c9a3f47d3aa9dc1fb99a2f6edff0703ff55742d2475ea2703c2b8d479221c6df53bf50c9832c94501597a65c40858b4f6
# output
address: mwjkhU9ZdoShS7wPKgj7dE8DnKgdRypoYh

router mechanism

  1. Swapout from btc to other chain

user send asset to mpc address with memo of the following format

bindAddress:toChainID

example:

0x1111111111111111111111111111111111111111:4

to specify route asset to which address (bindAddress) and to which destination blockchain (toChainID)

  1. Swapin from other chain to btc
function anySwapOut(address token, string memory to, uint amount, uint toChainID)

to is the destination on btc, it can be an btc address

btc tools

use -h option to get help info for each tool

example:

go run tokens/btc/tools/pubKeyToAddress/main.go -h

pubKeyToAddress
	convert ec public key to btc address

wifToEcPrivKey
	convert wif to ec privKey

config example: tokenConfig: [ { chainID: "1000004346948", tokenAddr: "btc", decimals: 8, version: 6, routerContract: "mwjkhU9ZdoShS7wPKgj7dE8DnKgdRypoYh", extra: "" } ] chainConfigs: [ { chainID: 1000004346948, blockChain: "btc", routerContract: "mwjkhU9ZdoShS7wPKgj7dE8DnKgdRypoYh", confirmations: "1", initialHeight: "5", extra: "" }, { chainID: 4, blockChain: "rinkeby", routerContract: "0x585DEa293B5c9dfe3E44976FD1A724e11CD7Cc21", confirmations: "15", initialHeight: "10781362", extra: "" }, ]
