Compilation & Deployment Guide

Aptos(TODO: Update)

Aptos CLI version >=1.0.0

see the latest guide in:

https://aptos.dev/cli-tools/aptos-cli-tool/use-aptos-cli

• step 0x01: run a local testnet

aptos node run-local-testnet --with-faucet

• step 0x02: create an account

aptos init --profile local --rest-url http://localhost:8080 --faucet-url http://localhost:8081
export PROFILE=local

Tips -- reset local network

aptos node run-local-testnet --with-faucet --force-restart

• step 0x03: get faucet

aptos account fund-with-faucet --profile $PROFILE --account $PROFILE

• step 0x04: compile contract

aptos move compile --package-dir [path]/MoveDID/did-aptos --named-addresses my_addr=$PROFILE

• step 0x05: deploy

aptos move publish --package-dir [path]/MoveDID/did-aptos --named-addresses my_addr=$PROFILE --profile $PROFILE

• step 0x06: init addr_aggr

aptos move run --function-id 1f9aa0aa17a3c8b02546df9353cdbee47f14bcaf25f5524492a17a8ab8c906ee::addr_aggregator::create_addr_aggregator --profile $PROFILE

• step 0x07: init endpoint_aggr

aptos move run --function-id 1f9aa0aa17a3c8b02546df9353cdbee47f14bcaf25f5524492a17a8ab8c906ee::addr_aggregator::create_endpoint_aggregator --profile $PROFILE

• step 0x08: add addr

aptos move run --function-id 1f9aa0aa17a3c8b02546df9353cdbee47f14bcaf25f5524492a17a8ab8c906ee::addr_aggregator::add_addr --args u64:0 --args String:a5928A4b811b6F850e633Dfb9f9c4B50247565a9 --args String:Ethereum --args String:Test --profile

• step 0x09: update addr for add new type

Test

Run Test in Contract:

aptos move test  --package-dir did-aptos  --named-addresses my_addr=0x123

Guide of New Module Addition

0x01: add new chain type module file, like addr_eth.move; add constant variable and implement update_addr fun.

example:

//eth addr type
const ADDR_TYPE_ETH: u64 = 0;

//eth addr length
const ETH_ADDR_LEGNTH: u64 = 40;

// err enum
const ERR_INVALID_ETH_ADDR: u64 = 2001;

public fun update_addr(addr_info: &mut AddrInfo, signature : &mut String) {
    ...
}

0x02: continue the second step, put the third step update_addr to the specify chain's update_*_addr fun.

example:

public entry fun update_eth_addr(acct: &signer,
      addr: String, signature : String) acquires AddrAggregator {
      ...
       while (i < length) {
         let addr_info = vector::borrow_mut<AddrInfo>(&mut addr_aggr.addr_infos, i);

         if (addr_info::equal_addr(addr_info, addr)) {
            addr_eth::update_addr(addr_info, &mut signature);
            break
         };
         i = i + 1;
      };
      ...
}
