Most wallets treat a single address as your entire onchain identity. It’s a simple way to onboard new users but longer-term it creates a limited mental model of what’s possible with keys. Power users often move funds between many wallets for security, testing, or airdrop hunting, which typically requires scripts or manual effort.

With Keychains, Doormat makes multi-wallet coordination as easy as three clicks. Create and control up to 100 Solana or EVM keys that move in sync. Fund, drain, swap, or transact across all of them at once.

Keychains are a new primitive inside Doormat that lets you generate and manage many wallets at once. You can create Keychains for Solana or EVM and choose how many addresses you want (from 2 to 100). Each address inside your Keychain can take actions independently, like buy, sell or swap, or move together in sync.

Each Keychain supports four primary actions:

Fund: Your keychain can receive assets from any Doormat key and distribute them across every address on your Keychain with a single click.

Drain: Instantly collapse all balances back to one key when you’re finished with a Keychain.

Echo Transact: Execute the same transaction across every address simultaneously. When you connect to a dApp, Doormat can multiply signature requests across your entire Keychain. (Currently available on EVM only)

Swap: Swap tokens across every address at once using Doormat’s built-in swapper. (Currently available on Solana only)

Each Keychain is backed by a single (2,2) MPC shard pair, one shard held by the user and one by Doormat. Instead of creating new shard pairs for every wallet, Doormat derives multiple addresses from this root using non-hardened BIP-32 paths. Each derived address stays isolated in use but inherits the same security guarantees as the root.

This structure lets one secure key generate up to 100 addresses with almost no performance overhead. Users can fund, drain, or sign across all addresses instantly, without weakening MPC protections or creating new key material.

Keychains make it easy to run high-volume, multi-address transactions safely. Our beta testers find them most helpful for points farming, bootstrapping token communities, and unlocking NFT mint limits. It’s a simple feature that unlocks advanced coordination onchain from directly inside Doormat.

Keychains are available today on both Solana and EVM. We’re excited for you to experiment, explore, and push what’s possible on Doormat.

Doormat v2.1 is currently available in a play-to-enter alpha. Check it out and ping us with your feedback! File all bugs/feature requests in Trevor’s DMs.
