Deployment guide

Set parameters

  1. Ensure the network config file deployment-configs/networks/[networkName].json has the correct global parameters
  2. Ensure the pool config file deployment-configs/pools/[networkName]/[poolName].json has the correct pool-scope parameters
    • Can just copy a config file from another pool. Need to make sure that EMAInitial, stablecoin, moneyMarketParams, and MinDepositAmount are updated correctly, as well as the pool names.
  3. Ensure the protocol config file deployment-configs/protocols/[networkName]/[moneyMarketName].json has the correct protocol specific addresses
    • Even if the protocol doesn't have protocol specific addresses, the file still must be created, with {} as the content.

Deploy DInterest pool

Put the array of configs (in the format of deployment-configs/config.json) of the pools you want to deploy in scripts/deploy-pool-list.json. The list of configs should be in the following format:

[
    {
        "network": "mainnet",
        "pool": "aave-dai",
        "protocol": "aave"
    },
    {
        "network": "mainnet",
        "pool": "aave-usdc",
        "protocol": "aave"
    },
    ...
]

Note that the configs must have the same network field. Then, execute the following script:

scripts/deploy-mainnet.sh [networkName]

Output subgraph config

Once new pools have been deployed, they should be added to the subgraph for indexing. To generate the configs automatically, scripts/output-subgraph.js is used.

First, put the list of pool configs in scripts/output-subgraph-configs.json in the following format:

{
    "network": "avalanche",
    "pool": "aave-dai",
    "protocol": "aave",
    "decimals": 18
  },
  {
    "network": "avalanche",
    "pool": "aave-usdc",
    "protocol": "aave",
    "decimals": 6
  },
  ...

where decimals is the number of decimals used by the underlying deposit token. Then, run:

npx hardhat run scripts/output-subgraph.js

The config will be output to stdout.

Notes

LinearDecayInterestModel

The interest amount as a function of the deposit length is a quadratic function that peaks at t_mid = interestRateMultiplierIntercept / (2 * interestRateMultiplierSlope). In order to ensure the interest amount monotonically increases, we must have t_max <= t_mid, which means interestRateMultiplierSlope <= interestRateMultiplierIntercept / (2 * t_max).
