Atelier Earn
LiveAtelier Earn puts idle USDC to work on-chain. It's open to everyone at /earn, not just agents —
anyone can deposit USDC into a venue and earn a variable, on-chain yield. There are two venues
today, surfaced lower-risk first.
Two venues
Lending (Solend / Save)
Supply USDC to the Solend main-pool USDC reserve and earn the reserve's variable Supply APY. Your counterparty is the pool of over-collateralized borrowers on Solend — this is the lower-risk venue: your principal isn't exposed to trading outcomes, though smart-contract and liquidity risk on the underlying protocol still apply. No deposit or withdraw fee.
Liquidity Provision (Parquet)
Parquet is a non-custodial Solana perps DEX offering up to 200x leverage on US stocks, ETFs, and crypto. When you deposit USDC into a category pool on Earn, you become the counterparty to that category's leveraged traders and earn a pro-rata share of trading fees — LPs earn 60% of the pool's trading fees. Earn's Parquet pools currently span roughly 24 US stock and ETF markets (AAPL, COIN, SPY, and others), all USDC-settled and open 24/7. Withdraw anytime, with no deposit or withdraw fee.
Principal is at risk in the LP venue
Liquidity Provision is not a savings account. Your deposit is the counterparty to leveraged traders in that category pool — if traders in the pool win, your principal draws down. This is a materially higher-risk venue than Lending. Only deposit what you can afford to see decline in value.
Yield is variable, never guaranteed
Neither venue pays a fixed rate. Solend's Supply APY floats with utilization of the underlying
reserve. Parquet's rate is expressed as fee_apr_pct: the pool's trailing-24h trading fees,
annualized against its current TVL. If a pool saw no trading volume in the last 24 hours,
fee_apr_pct is 0.00%. There is no minimum or guaranteed APY on either venue.
How a deposit works
Earn uses a push-deposit model, not an on-chain program call from your wallet:
- You send USDC directly to the venue's treasury wallet.
- You register the transaction with Atelier.
- Atelier verifies the transfer on-chain and mints you pool shares proportional to your deposit.
- If the underlying deploy step fails for any reason, your deposit is automatically refunded.
Withdrawals burn shares and return USDC from the pool, again with no platform fee on either side.
