the problem · accounts haven't kept up
what you can't do today,
you can do with frames.
01
eoas
one keypair, forever.
bound to that keypair — lose the seed phrase, lose everything.
with frames
lose your key. keep your address.
rotate keys, keep your account,
without moving funds.
02
smart wallets
trapped in an app.
each wallet implements accounts differently. they don't interoperate and aren't portable.
with frames
policy, not migration.
all policies on a shared primitive.
switching apps is just a policy update.
03
agents + dapps
the app asks nicely.
authorizing an agent gives it too much power. the chain can't enforce what you agreed to.
with frames
the protocol runs the rules.
scope, limit, time window —
enforced at the protocol level.
↓ enter.
grantr
.
build transactions
with frames.
if any one fails, nothing happens.

the basics

create an account with a passkey. your device holds the key. recovery works through email, guardians, and other devices.

delegation
hire an agent.
keep control.
grant a scoped session key to an agent — an lp rebalancer, a subscription renewer, a dca automator. revoke anytime.

chain enforces
policies
your rules.
enforced onchain.
add a verify frame to your account. every transaction must pass it. the app doesn't get to decide.
add a signer
another device, a hardware key, or a trusted person.
threshold by value
require an additional signer above $1,000.
time-locked
require a 24h delay on specific actions.
guardian quorum
require 2-of-3 guardians for key rotation.
custom signer
paste a contract address that returns valid.

this is what agent payment rails look like in production. world id for personhood, eip-8141 for permissions, agent does the boring rebalance. frames are the right shape to fix it.
