Eco’s Permit3 Is Now Live on Para: Seamless Cross-Chain Permissions for Any Wallet

Today, Eco’s Permit3 is integrated with Para Transaction Permissions, enabling any Para customers or businesses to authorize complex cross-chain actions with a single click. 

Before Para, crypto users faced frustrating complexity when trying to complete their desired onchain transaction. With approvals, every asset must be approved before use. This complexity quickly multiplies when considering cross-chain transfers: every asset needs to be approved for use on each blockchain. This means that every cross-chain action requires countless wallet approvals for a single transaction. 

Para brought the confirmation layer, specifically a clear UI that shows users exactly what’s being signed and from which wallet and chain. Eco brings Permit3, which treats authorization the way modern software should: as a scoped, time-bound contract tied to a specific action a user is trying to take. 

The Onchain Authorization Problem, Solved

Onchain approvals have always been a weak link in crypto UX. The experiences designed around approvals have taken them literally: every type of approval is prompted to the user, rather than making approvals as simple and easy as possible.

Traditional token approvals behave like the worst version of OAuth: unclear scope, overly broad access, hard to audit, and easy to forget. Users grant more than they understand and can't easily take it back. Imagine “signing in with Google” and as a result turning over not only troves of personal data, but also unbounded access to potentially also swipe your credit card.

Permit3 treats authorization the way modern software should, as a scoped, auditable, time-bound contract between the user and the action they're actually trying to take. Permit3 is specifically designed for multi-token, multi-chain user journeys.

Instead of:

• Approve token
• Sign transaction
• Wait
• Sign another transaction
• Bridge
• Sign again

You get:

• User grants a scoped permission tied to the specific action
• User sees exactly what they're authorizing in Para's confirmation UI
• The system executes within the agreed boundaries, across chains

The permission is limited to the exact assets, contracts, chains, amounts, and time windows required by the action. It expires when it should. It can be revoked. What the user approves is exactly what executes.

What Onchain App Builders Can Do With It

Batched cross-chain actions, made legible and executable

Onchain workflows are rarely a single step. A user's funds might be on Arbitrum while the action they want to take is on Base. Or they're depositing into a yield protocol that touches multiple assets, chains, and contracts. Today, that means a gauntlet of prompts — wallet approvals, bridge signatures, gas decisions — most of which are opaque to the user. For compliance teams, that opacity is a liability — without clear metadata on what was authorized, by whom, and under what conditions, these flows can't be audited, approved, or safely scaled.

With Permit3 integrated into Para Transaction Permissions, the entire scope of an action is defined upfront, constrained to specific assets, protocols, caps, and time windows, and surfaced clearly in Para's confirmation UI. The user sees exactly what they're authorizing. Permit3 executes it. No additional signatures, no chain-switching, no guesswork.

This matters beyond UX. Institutional and compliance-sensitive users won't rely on onchain authorization flows that are error-prone or lack the metadata they need to approve an action with confidence. Scoped, auditable permissions change that.

Repeat authorizations with real guardrails

Some flows require authorization for actions that happen more than once — scheduled payments, recurring deposits, and automated settlements. Permit3 enables "set it once" authorization with enforced limits: expiry, revocation, allowlists, and runtime policy checks. The authorization is reusable only within the bounds the user agreed to, and every approval runs through Para's confirmation layer.

Permit3 is open source, and this use case with Para is one example of what's possible when authorization is treated as a first-class design problem. If you're building cross-chain flows and want to explore what a co-designed integration could look like, we'd love to hear from you.
