What is wallet_addEthereumChain JSON?

wallet_addEthereumChain JSON is the parameter object a site can pass to a wallet when requesting a custom EVM network addition.

Does Main.net connect to a wallet from this page?

No. Main.net renders manual JSON examples and does not call wallet APIs, request permissions, or submit transactions.

What is the MegaETH EIP-3085 chainId value?

MegaETH mainnet uses chain ID 4326 / 0x10e6, so its EIP-3085 chainId value is 0x10e6.

Guide

Copy wallet_addEthereumChain JSON examples

Copy a wallet_addEthereumChain object, check the chain ID and nativeCurrency fields, then verify the RPC and explorer against source docs. Main.net renders text only; this page does not connect wallets or request permissions.

Quick settings

Build a wallet JSON snippet

These manual wallet_addEthereumChain examples are generated from Main.net chain IDs, RPC URLs, explorers, and nativeCurrency name, symbol, and decimals fields. Base uses 0x2105, Polygon PoS uses 0x89, Arbitrum One uses 0xa4b1, OP Mainnet uses 0xa, and MegaETH uses 0x10e6.

Local inspector

Inspect wallet config JSON

Paste an EIP-3085 parameter object to validate its shape and compare its chain ID, RPC, explorer, icon, network name, and currency symbol with the Main.net source snapshot. Currency name and decimals appear in a separate unverified convention comparison.

EIP-3085 JSON

Runs in this page only. Pasted JSON is not transmitted. No wallet connection or RPC call is made.

Unverified conventions: Main.net synthesizes nativeCurrency.namefrom the source-backed symbol and uses 18 for nativeCurrency.decimals. The inspector labels both fields separately from source-backed values.

How to use these snippets

Compare the chain ID, RPC URL, explorer URL, and gas token against the linked source documentation.
Confirm nativeCurrency.name, nativeCurrency.symbol, and nativeCurrency.decimals are present before using the object in a wallet request.
Use these snippets as text references for app configuration or manual wallet setup review.
Do not treat a public RPC URL as a production reliability, privacy, or uptime guarantee.

Common wallet_addEthereumChain checks

These checks target the common failure mode behind searches likenativeCurrency name required. Main.net keeps the fields visible so teams can validate the object before calling wallet APIs.

Missing nativeCurrency fields: Include name, symbol, and decimals. Main.net renders decimals as 18 for reviewed EVM mainnet rows.
Wrong chainId format: Use hexadecimal chain IDs for EIP-3085, such as 0x2105 for Base or 0xa for OP Mainnet.
Network not added: If a wallet reports an unknown chain during a switch flow, compare the chain ID and then use a reviewed add-network object.
Pending wallet request: Only make one wallet-add or network-switch request at a time; repeated prompts can be rejected by wallet software.

Before you call a wallet API

EIP-3085 defines wallet-network request parameters, but this page never calls a wallet API. The safest flow is to copy values, verify them against source documentation, and decide inside your own application or wallet flow.

EIP-3085 wallet config questions

What is wallet_addEthereumChain JSON?: wallet_addEthereumChain JSON is the parameter object a site can pass to a wallet when requesting a custom EVM network addition.
Does Main.net connect to a wallet from this page?: No. Main.net renders manual JSON examples and does not call wallet APIs, request permissions, or submit transactions.
What is the MegaETH EIP-3085 chainId value?: MegaETH mainnet uses chain ID 4326 / 0x10e6, so its EIP-3085 chainId value is 0x10e6.
