# Send Megaeth Developer to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### What this Skill is for

Use this Skill when the user asks for:

Wallet setup and management on MegaETH
Sending transactions, checking balances, token operations
Token swaps via Kyber Network aggregator
MegaETH dApp frontend (React / Next.js with real-time updates)
RPC configuration and transaction flow optimization
Smart contract development with MegaEVM considerations
Storage optimization (avoiding expensive SSTORE costs)
Gas estimation and fee configuration
Testing and debugging MegaETH transactions
WebSocket subscriptions and mini-block streaming
Bridging ETH from Ethereum to MegaETH

### Chain Configuration

NetworkChain IDRPCExplorerMainnet4326https://mainnet.megaeth.com/rpchttps://mega.etherscan.ioTestnet6343https://carrot.megaeth.com/rpchttps://megaeth-testnet-v2.blockscout.com

### 1. Transaction submission: eth_sendRawTransactionSync first

Use eth_sendRawTransactionSync (EIP-7966) — returns receipt in <10ms
Eliminates polling for eth_getTransactionReceipt
Docs: https://docs.megaeth.com/realtime-api

### 2. RPC: Multicall for eth_call batching (v2.0.14+)

Prefer Multicall (aggregate3) for batching multiple eth_call requests
As of v2.0.14, eth_call is 2-10x faster; Multicall amortizes per-RPC overhead
Still avoid mixing slow methods (eth_getLogs) with fast ones in same request

Note: Earlier guidance recommended JSON-RPC batching over Multicall for caching benefits. With v2.0.14's performance improvements, Multicall is now preferred.

### 3. WebSocket: keepalive required

Send eth_chainId every 30 seconds
50 connections per VIP endpoint, 10 subscriptions per connection
Use miniBlocks subscription for real-time data

### 4. Storage: slot reuse patterns

SSTORE 0→non-zero costs 2M gas × multiplier (expensive)
Use Solady's RedBlackTreeLib instead of Solidity mappings
Design for slot reuse, not constant allocation

### 5. Gas: skip estimation when possible

Base fee stable at 0.001 gwei, no EIP-1559 adjustment
Ignore eth_maxPriorityFeePerGas (returns 0)
Hardcode gas limits to save round-trip
Always use remote eth_estimateGas (MegaEVM costs differ from standard EVM)

### 6. Debugging: mega-evme CLI

Replay transactions with full traces
Profile gas by opcode
https://github.com/megaeth-labs/mega-evm

### 1. Classify the task layer

Frontend/WebSocket layer
RPC/transaction layer
Smart contract layer
Testing/debugging layer

### 2. Pick the right patterns

Frontend: single WebSocket → broadcast to users (not per-user connections)
Transactions: sign locally → eth_sendRawTransactionSync → done
Contracts: check SSTORE patterns, avoid volatile data access limits
Testing: use mega-evme for replay, Foundry with --skip-simulation

### 3. Implement with MegaETH-specific correctness

Always be explicit about:

Chain ID (4326 mainnet, 6343 testnet)
Gas limit (hardcode when possible)
Base fee (0.001 gwei, no buffer)
Storage costs (new slots are expensive)
Volatile data limits (20M gas after block.timestamp access)

### 4. Deliverables expectations

When implementing changes, provide:

Exact files changed + diffs
Commands to build/test/deploy
Gas cost notes for storage-heavy operations
RPC optimization notes if applicable
