PlatON Devnet Skills

TIP

This guide covers setting up the PlatON development network for Nexus integration testing.

Prerequisites

• Node.js 24+
• Foundry toolchain (forge, cast, anvil)
• A funded wallet on PlatON Devnet (chainId: 20250407)

Network Configuration

Parameter	Value
Chain ID	20250407
RPC URL	https://devnet3openapi.platon.network/rpc
Block Explorer	Blockscout-based
USDC Contract	0xFF8dEe9983768D0399673014cf77826896F97e4d
Escrow Proxy	0xeB33a9C2b4c7D3F44Fd5514F90C355AF6bb79236

Important: Millisecond Timestamps

PlatON Devnet uses block.timestamp in milliseconds inside the EVM, despite the RPC layer returning seconds. This affects all on-chain timestamp comparisons:

• EIP-3009 validBefore / validAfter must be in milliseconds
• Escrow releaseDeadline / disputeDeadline are computed from block.timestamp

Foundry Usage on PlatON

PlatON requires the --legacy flag for transaction broadcasting:

forge script Deploy.s.sol \
  --rpc-url https://devnet3openapi.platon.network/rpc \
  --broadcast \
  --legacy \
  --with-gas-price 20000000000

WARNING

EIP-1559 transactions get 1 wei gas price on PlatON, which is too low. Always use --legacy.

Skills Overview

Five developer skills are available for PlatON devnet interaction:

1. chainlist — Network configuration and chain metadata
2. cli (cast) — Command-line interaction with contracts
3. blockscout — Block explorer queries and verification
4. crosschain — Cross-chain bridge operations
5. aawallet — Account abstraction wallet management
