Base Yield Savings: a 3.5% APY product, by default
Base Yield Savings pays a target interest rate of 3.5% a year on your full USDT balance, across both your funding and trading accounts. Grvt sets the rate in advance, so it does not move with the market.
Accrues daily. Your balance earns every day at the fixed rate, from deposit to withdrawal.
No conditions. No minimum trades, no volume tiers, no activation steps.
No lockup. Your balance stays fully usable. Trade with it, withdraw it, or move it at any time while it earns.
Paid in USDT. All yield payouts are denominated and paid in USDT.
USDC support is coming. We are adding USDC support, so your USDC balance will also earn the base yield.
Where the yield comes from
Base Yield comes from the platform's idle reserves. Today those reserves sit mostly in the Aave and GHO protocols, two of the deepest and longest-running yield sources in DeFi. In the future, we may add tokenized real-world assets. You can check the current sources on the Earn on Equity page.
Every yield source must pass a strict framework before we commit a single dollar:
Battle-tested: Audited protocols with long operating histories and far more capital than we deploy.
On-chain verifiable: You can verify our positions on-chain, not take them on faith.
Instant redemption: We can pull capital back to USDT on demand.
Sustainable sourceThe yield comes from real lending activity.
This discipline lets the program scale: the underlying protocols hold tens of billions in liquidity, so growth in Grvt deposits does not dilute your rate, and there is no hard cap on the equity that earns.
How it works under the hood
Your balance lives on Grvt L2, Grvt's own chain that settles on Ethereum. It stays under self-custody. Only excess platform reserves above a safety buffer move down to the Grvt Layer 1 smart contract on Ethereum, which deploys them to Aave and GHO each day. The contract can only interact with whitelisted protocols: today that means Aave and GHO, each approved per asset with its own cap. In the future the whitelist may include tokenized real-world assets. In the diagram, deposits flow down the left and withdrawals flow up the right of the same path.
Three things are worth underlining. First, the daily cycle runs on both sides: the contract deploys capital daily, and your yield accrues daily. Second, the rate is fixed, so daily moves in protocol yields never show up in what you earn. Third, withdrawals never wait on the yield: most are instant, and we picked sources we can pull back on demand.
How it is secured
Grvt runs on its own Layer 2 blockchain, secured by zero-knowledge proofs posted to Ethereum.
Self-custody. You sign every on-chain transaction with your own private key. Grvt cannot move your funds without you.
Provable integrity. ZK proofs verify every state change on Ethereum. No one can fabricate balances or forge trades.
Whitelisted protocols only. The Grvt Layer 1 smart contract can only interact with whitelisted protocols. Today the whitelist holds Aave and GHO, each approved per asset with its own cap. In the future it may include tokenized real-world assets. Reserves cannot go anywhere else.
Battle-tested sources only. Base Yield deploys only to audited protocols that pass the framework above, and you can verify every position on-chain via the Earn on Equity page.
Want to reach further? Meet the bundles
For savers who want more than the base rate, two curated bundles are now open in beta. Both hold real-world assets managed by named institutions, and both are opt-in from the Earn page.
Balanced Bundle, targeting 4.5%. The conservative step up, backed by credit managed by BlackRock. Most savers start here.
Opportunistic Bundle, targeting 11%. The reach, backed by investment-grade receivables managed by BlackOpal. More yield, more risk.
You can hold both, in any amounts you choose. Capacity is limited while the beta runs, and target returns are targets, never guarantees.
Base Yield Savings stays untouched either way: your 3.5% keeps accruing daily on whatever you leave in your balance.
Getting started
Every USDT deposit earns the fixed 3.5% from day one. To go further, open the Earn page and join the Balanced or Opportunistic Bundle beta.
