Latch

Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

Latch is a cross-chain yield product using Ethereum vault deposits and Gravity receipt tokens. Users deposit idle tokens into a chosen vault and earn yield plus points. TVL was about $1.58 million at the 2026-08-15 survey, far under our $100 million materiality line. Rejected on size: one practice advising 100 households moves $1M to $8M into a venue on the same research, and below $100M TVL that book becomes the exit crush. Size alone decides it, whatever the protocol’s quality. Sustained growth reopens the file.

The research file

Mechanism applicability

Latch Smart Savings routes deposited USDT or ETH into DeFi vaults and issues value-accruing atUSD or atETH receipts representing a share of the underlying position. Primary deposits originate on Ethereum while receipts are minted and used on Gravity; secondary paths may bridge and swap from other EVM chains. The current tracked vault balance, rather than the broader interoperability roadmap, establishes applicability to the shared v1 below-materiality dossier.

Current observation and perimeter

The DefiLlama protocol API read on 2026-08-15 classified Latch as Yield and reported approximately $1.58M on Ethereum. Current Latch documentation identifies Gravity as the Smart Savings and receipt-token layer, while Ethereum holds the primary-market deposits and claims. The registry therefore records both Ethereum and Gravity; the protocol remains documented and its savings interface is reachable, although the public docs retain forward-looking language for some omnichain functions.

Control and exit applicability

Vault strategy performance, bridges, Gravity receipt accounting, and Latch routing all sit between a user and underlying assets. Primary withdrawal burns atUSD or atETH on Gravity and claims on Ethereum after a stated waiting period usually around seven days; secondary exit depends on DEX liquidity and bridging. Terms also permit protocol-specific bonding, locking or claim delays and service or transaction-fee deductions.

Why the class rule decides

At roughly $1.58M survey TVL, a $1M to $8M advised book would dominate the tracked vault before the cross-chain withdrawal path is stressed. The shared v1 below-materiality dossier therefore decides. Reopen after DefiLlama TVL remains above $100M for 30 consecutive days, then verify deployed vault strategies, Ethereum and Gravity contracts and operators, bridge and routing controls, incidents, proposed-size primary and secondary exits, legal terms, and named single-chain alternatives.

Inherited controls

The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
