Sky Protocol
Overview
Documentation for Sky Protocol integration and usage within the KeeperHub ecosystem.
Sky (formerly MakerDAO) is a decentralized protocol for stablecoin savings, governance, and token migration. This plugin provides actions for depositing into the USDS savings rate vault (sUSDS), checking token balances, managing approvals, and converting legacy DAI/MKR tokens to their successors USDS/SKY. Supported chains: Ethereum (all contracts), Base (USDS, sUSDS), Arbitrum (USDS, sUSDS). Read-only actions work without credentials. Write actions require a connected wallet.
Deposit USDS to Savings
Deposit USDS into the sUSDS savings vault (ERC-4626). Shares are minted to the receiver proportional to the current exchange rate. Inputs: Outputs: success, transactionHash, transactionLink, error
success
transactionHash
transactionLink
error
When to use: Earn yield on idle USDS, automate savings deposits after receiving funds, compound rewards by depositing periodically.
Withdraw USDS from Savings
Withdraw a specific amount of USDS from the sUSDS savings vault. Burns the corresponding shares from the owner. Inputs: Outputs: success, transactionHash, transactionLink, error
success
transactionHash
transactionLink
error
When to use: Withdraw savings when funds are needed, automate partial withdrawals based on conditions.
Redeem sUSDS Shares
Redeem a specific number of sUSDS shares for the underlying USDS. The amount of USDS received depends on the current exchange rate. Inputs: Outputs: success, transactionHash, transactionLink, error
success
transactionHash
transactionLink
error
When to use: Exit savings position entirely, redeem a specific share amount rather than a target USDS amount.
Get sUSDS Balance
Check the sUSDS balance of any address on supported chains. Inputs: Outputs: When to use: Monitor savings positions, track sUSDS holdings across wallets, trigger actions based on balance thresholds.
Preview Savings Deposit
Preview how many sUSDS shares a given USDS deposit would yield at the current exchange rate. Does not execute a transaction. Inputs: Outputs: When to use: Calculate expected shares before depositing, display savings rate information, compare rates across vaults.
Get USDS Value of sUSDS
Convert sUSDS shares to their underlying USDS value at the current exchange rate. Does not execute a transaction. Inputs: Outputs: When to use: Calculate the current value of a savings position, monitor accrued yield, display portfolio values in USDS terms.
Get USDS Balance
Check the USDS stablecoin balance of any address. Inputs: Outputs: When to use: Monitor USDS holdings, check wallet balances before initiating savings deposits or conversions.
Get DAI Balance
Check the DAI stablecoin balance of any address (Ethereum only). Inputs: Outputs: When to use: Monitor legacy DAI holdings, identify wallets that should migrate from DAI to USDS.
Get SKY Balance
Check the SKY governance token balance of any address (Ethereum only). Inputs: Outputs: When to use: Monitor SKY token holdings, track governance power, verify migration from MKR to SKY.
Approve USDS Spending
Approve a spender address to transfer USDS on your behalf. Required before depositing USDS into the savings vault or other contracts. Inputs: Outputs: success, transactionHash, transactionLink, error
success
transactionHash
transactionLink
error
When to use: Approve the sUSDS contract before depositing, set allowances for DeFi protocols, manage token permissions.
Approve DAI Spending
Approve a spender address to transfer DAI on your behalf. Required before converting DAI to USDS. Inputs: Outputs: success, transactionHash, transactionLink, error
success
transactionHash
transactionLink
error
When to use: Approve the DAI-USDS converter before migrating, set allowances for DeFi protocols.
Convert DAI to USDS
Convert DAI to USDS at a 1:1 rate via the official Sky Protocol converter. Ethereum only. Requires prior DAI approval for the converter contract. Inputs: Outputs: success, transactionHash, transactionLink, error
success
transactionHash
transactionLink
error
When to use: Migrate DAI holdings to USDS, automate batch DAI-to-USDS conversions, prepare funds for sUSDS deposits.
Convert USDS to DAI
Convert USDS back to DAI at a 1:1 rate via the official Sky Protocol converter. Ethereum only. Requires prior USDS approval for the converter contract. Inputs: Outputs: success, transactionHash, transactionLink, error
success
transactionHash
transactionLink
error
When to use: Convert USDS back to DAI for protocols that only accept DAI, manage liquidity across both stablecoins.
Convert MKR to SKY
Convert MKR governance tokens to SKY via the official Sky Protocol converter. Ethereum only. This is a one-way conversion. Inputs: Outputs: success, transactionHash, transactionLink, error
success
transactionHash
transactionLink
error
When to use: Migrate MKR holdings to the new SKY governance token, automate MKR-to-SKY conversion for treasury management.
Monitor USDS Balance with Alert
Schedule (daily) -> Sky: Get USDS Balance -> Math (Sum, divide by 1e18) -> Condition (< 100) -> Discord: Send Message
Schedule (daily) -> Sky: Get USDS Balance -> Math (Sum, divide by 1e18) -> Condition (< 100) -> Discord: Send Message
Check your USDS balance daily, convert from wei to decimal, and send a Discord alert if it drops below 100 USDS.
Deposit Idle USDS into Savings
Schedule (hourly) -> Sky: Get USDS Balance -> Math (Sum, divide by 1e18) -> Condition (> 500) -> Sky: Approve USDS Spending -> Sky: Deposit USDS to Savings
Schedule (hourly) -> Sky: Get USDS Balance -> Math (Sum, divide by 1e18) -> Condition (> 500) -> Sky: Approve USDS Spending -> Sky: Deposit USDS to Savings
Periodically check for idle USDS and automatically deposit into the sUSDS savings vault when the balance exceeds a threshold. Requires wallet connection.
Track Savings Yield
Schedule (daily) -> Sky: Get sUSDS Balance -> Sky: Get USDS Value of sUSDS -> Math (Sum, divide by 1e18) -> HTTP Request (POST to webhook)
Schedule (daily) -> Sky: Get sUSDS Balance -> Sky: Get USDS Value of sUSDS -> Math (Sum, divide by 1e18) -> HTTP Request (POST to webhook)
Monitor your sUSDS position, convert shares to their current USDS value, and send the result to an external webhook for portfolio tracking.

One-click migration of DAI holdings: check balance, approve the converter, convert to USDS, and deposit into savings. Ethereum only.
The savings vault (sUSDS) and USDS stablecoin are available on all three chains. DAI, SKY, and the converter contracts are Ethereum-only. Rocket Pool Spark
