Today we’re uncovering something that makes interop truly invisible. It lets users from any chain — Solana, Ethereum, wherever — pay and transact on Push Chain using their native tokens like SOL or any token they choose like JUP. All in one transaction. Without ever leaving their home chain. 🤯 Meet the invisible magic that powers it all 👇 Universal Executor Accounts (UEAs)

“UEA”? Sounds like a country next to UAE 🇦🇪 Not quite. Let’s see why UEAs make both DevX and UX smoother: - Tim wants to use a Universal DeFi protocol on Push Chain using his Solana wallet - Push Chain (being EVM compatible) expects Ethereum-style addresses (0x...) and ECDSA signatures - But - Solana Wallet uses base58 addresses and Ed25519 signatures Here’s where things get interesting 👇

Naturally, EVMs can’t read Solana address formats. So Tim’s transaction would fail, unless he: 1️⃣ Bridges assets to an EVM chain (painful UX) 2️⃣ Finds a miracle that allows txns between two incompatible systems That miracle exists now. It’s called Universal Executor Accounts (UEAs) and they act as intelligent intermediaries between incompatible chains. How do they work? 👇

UEAs are smart accounts on Push Chain tied to users’ external (native) wallet addresses. Their purpose? - They translate Tim’s Solana address into an EVM-compatible format - They execute the action initiated by Tim’s Solana address - All the while fully maintaining signing, verification, and attribution to Tim’s original Solana identity! The benefit 👇

The benefit: - The app developer never needs to touch the cross-chain handling or interop logic 🧙 - The user never needs to learn bridges, wallet standards, or gas 🦸 The chain handles interop. The app inherits it. Builders build apps. Users use them. Chain does the wizardry. Your app is now native to every chain. What does the user see? 👇

What the User Experiences 👇 Tim, a SOL native user, wants to buy a memecoin on a Universal Dex built on Push Chain. 1. Clicks "BUY $1000 worth of Memecoin” 2. Wallet shows: "Pay 5 SOL" (gas included) 3. Signs once 4. Transaction executes on Push Chain 5. Token appears in his multichain wallet. But what happens behind the curtains?👇

What User Doesn't See - The real behind-the-scenes magic: There are 3 key layers to this process: 1. Routing (Gas Handling) 2. Verification (Signature Validation) 3. Execution (Final Action on Push Chain) Got it — the chain is doing R.V.E. (Ridiculous Vibe Execution). Nope. let’s break it down 👇

1️⃣ Routing: Routing handles how the transaction moves through gas, fees, and block validation. This phase involves: - Gas Estimation: Based on the current value of users' native token, the SDK calculates the required amount of PC (Push Chain's native token) to pay the gas - Transaction Signing: Converts the gas, tallies the total txn cost, prepares and initiates the transaction payload, which is then signed by the user’s wallet cryptographically - Locking of Fees: This fee payment (in the user's native funds) is locked into the Universal Gateway Contract. These are contracts on external chains that facilitate fee and asset locking and unlocking. - Proof Verification: Gateway events are verified by consensus through Universal Validators (UVs), who then pass this to Push Chain’s Validators. - User Creation: Based on the new or returning user, Push validators create new UEA accounts or deposit to existing UEAs. Side note: Since the UEA is deterministically generated, the validators can derive addresses from a Solana or Ethereum address automatically to check if they are new or returning users. Let’s talk about V for Verification now 👇

2️⃣ Verification Verification of the txs is never offloaded to any third party. Each tx that lands in the UEAs smart account must always be accompanied with the signature from the native chain. The UAE, upon receiving a transaction request, sends the signature to a custom module in Push Chain that is called Universal Verification Layer (UVL). Its job is to verify whether the controller of the UEA is the same wallet that signed the transaction on the source chain. And validate if - user's private key did actually sign this transaction? On successful verification → signal is sent to the UEA to execute the transaction. Which leads us to… The Execution part 👇

3️⃣ Execution (Smart Account Execution) Once the signature is verified: - UEA executes the transaction using the instructions signed by the external wallet. - The execution is seamless and respects the rules/UX of the originating chain. Of course, all this happens under the hood. From the user’s perspective: - They simply interact using their native wallet. - Pay gas in their native token. - Execute cross-chain logic in a single flow. Let’s get to the best part, so that I can like the top and bottom and be done with this thread👇

🧠 TL;DR To summarise, with the help of UEAs: - Users: - Don’t need to bridge, switch wallets or networks for cross chain txns on Push Chain. - Pay in their own source chain’s native token or any other supported token of choice. - Execute multi-chain actions with one single signature. - Developers: - Spend comically minuscule time on infrastructure, more on app features. - Don’t deal with integrating complex bridging, signature formats, or wallet fragmentation workflows. - Don’t need to implement custom fee routing per chain. - Get interop out of the box. Invisible interop. Visible impact. 🧩
