@coraprotocol/leverage v1.0.3

cora-leveraged-staking

Release new version of this package

Smart contracts ABIs can be published as an NPM package.

yarn build

Will update the abis/ directory with the latest contracts ABIs. For new contracts that need to be exported, build.js needs to be modified (abisToExport array).

Local development environment

docker-compose up --build

That will start two containers:

• cora-leveraged-staking_rpc_1: this is just an Anvil. Docker hostname is rpc
• cora-leveraged-staking_deploy_1: Performs the initial migration to Anvil and it stays running in case more scripts need to be run

Scripts examples

Change an LSD mock rate (increasing it will simulate staking rewards):

docker exec cora-leveraged-staking_deploy_1 script/updateLsdMockStakingRate.sh http://rpc:8545 <lsd address> <new rate>

• The first argument is the RPC, we can keep http://rpc:8545 if we are running it against the local environment
• lsd address is the LSD mock address that we want to update
• <new rate> scaled to 18 decimals. For example if we want to set it as 1.2 we need to pass 1200000000000000000 as the argument.

Advance time

This will increase the time by an amount in seconds. Example, advance the time 1 hour

curl --location --request POST 'localhost:8545/' \
--header 'Content-Type: application/json' \
--data-raw '{
        "jsonrpc":"2.0",
        "method":"evm_increaseTime",
        "params":["3600"],
        "id":67}'

This will set the next timestamp. Example, this will set the next block timestamp to 1st Jan 2023:

curl --location --request POST 'localhost:8545/' \
--header 'Content-Type: application/json' \
--data-raw '{
        "jsonrpc":"2.0",
        "method":"evm_setNextBlockTimestamp",
        "params":["1672531200"],
        "id":67}'
