Universal apps look “easy” on the surface: connect any wallet, pay with any token, one click and done.
Behind that, something very unsexy makes all of this work: validators.
On Push Chain, validators don’t just produce blocks. They:
- Settle universal transactions coming from many chains
- Keep Universal Executor Accounts (UEAs) in sync and honest
- Help guarantee that “one click from Solana → action on Push” is actually safe
- They secure a chain that’s meant to be used by other chains’ users
Push Chain doesn’t rely on a single validator model.
It runs on a validator stack with two distinct roles, each designed for a different job.
1️⃣ Core ( Network) Validators
These secure the network, participate in consensus, and ensure the chain stays honest and live.
2️⃣ Universal Validators
These extend Push Chain beyond a single ecosystem, enabling shared state and cross-chain execution across EVM and non-EVM chains.
Why two distinct validators?
Because securing a chain and coordinating universal execution are very different problems — and Push Chain treats them as such.
This separation keeps the system:
• Modular
• Scalable
• Easier to reason about for builders
How They Work Together (High-Level Flow)
User locks 100 USDC on Ethereum
↓
Universal Validators observe the lock
↓
Multiple Universal Validators report to Push Chain
↓
Consensus reached on the external transaction
↓
Network Validators mint 100 pUSDC on Push Chain
↓
User receives pUSDC instantly. No bridging manually
Key security feature: Universal Validators operate under consensus. Multiple validators must agree on what happened on the external chain before Push Chain acts.
