Self-custody and yield stopped being a trade-off

Trezor just added native stablecoin yield to Trezor Suite – deposit $USDC or $USDT into a curated Morpho vault without leaving the app or connecting an external wallet. Every step, from deposit to withdrawal, gets clear-signed on the device itself.

It's not the first. Ledger added yield through Kiln in April 2025, routing into Aave and Compound. @Tangem followed in late 2025 with a direct line into Aave. Trezor went narrower: two vetted vaults curated by Steakhouse, picked on the user's behalf.

Worth noting: Vitalik Buterin has pointed out that plenty of stablecoin-yield products still carry counterparty exposure. Fair critique – self-custody removes one failure mode, not all of them.

What's clear is the pattern: storage and yield are settling into the wallet itself. Exchange is the layer that tends to get integrated rather than rebuilt – Tangem Express and the air-gapped ELLIPAL already route their swaps through SimpleSwap's 20+ liquidity providers.
