Introduction
Ether.cat is an all-in-one Ethereum token management and trading platform built for speed, privacy, and power. Whether you are managing wallets, sniping launches, or deploying tokens, everything lives in one place.
- Private Ethereum full node — no shared RPC, no rate limits, no latency
- Private transaction routing via bloXroute (all builders) and Flashbots
- Multi-wallet support across Ethereum and Base
- Real-time on-chain data: live block, gas, and ETH price in the header
- Role-based plan system — upgrade to unlock advanced tools
Plans & Access
Ether.cat uses a tier system to control access to features. Your tier is stored on-chain via your wallet's sign-in and can be upgraded by an admin.

Dashboard
The dashboard is your home base — an overview of your wallets, on-chain status, and quick-access tools.
- Aggregate ETH and token balances across all your wallets at a glance
- Live ETH price (via Chainlink) and gas fees (in Gwei) displayed in the header
- Current block number updated in real-time via WebSocket
- Quick links: personal shortcuts you can add, label, and organise
- Live connection indicator showing WebSocket status
Wallets
Ether.cat stores and manages your wallets server-side (encrypted private keys in Supabase), so they are available from any device after sign-in. Supported chains: Ethereum and Base.
- Generate new wallets — private key created server-side and stored encrypted
- Import existing wallets by pasting a private key
- View ETH balance and ERC-20 token balances per wallet
- Native ETH transfer between wallets (submitted privately via bloXroute/Flashbots)
- Disperse ETH to multiple wallets in a single transaction
- Transaction history log per wallet
- Muling — move tokens or ETH across wallets in sequence to obscure on-chain trail
Fast Swap
Fast Swap is a streamlined buy interface — paste a token contract address, choose a wallet, enter an ETH amount, and fire. The transaction is submitted privately so it cannot be front-run.
- Buy any ERC-20 token using ETH via Uniswap V2 routing
- Select from any of your imported wallets as the buyer
- Set ETH amount and optional slippage tolerance
- Private submission via bloXroute — invisible in the public mempool
- Fallback to Flashbots relay or MEV Blocker if bloXroute is unavailable
- Supports Ethereum and Base chains
Sell
The Sell page lets you track tokens across wallets and sell percentage-based positions with a single click.
- Import any ERC-20 token by contract address to start tracking it
- See live balance of the imported token across all your wallets
- Select one or multiple wallets to sell from simultaneously
- Choose the percentage of the holding to sell (e.g. 50%, 100%)
- Transactions submitted privately via the same routing as Fast Swap
- Per-token transaction history
Price Tracker
Monitor any ERC-20 token in real-time and get notified when price targets are hit.
- Add tokens by contract address — data sourced from DexScreener
- Live price, market cap, liquidity, and 24h volume displayed per token
- Set alerts: above a price, below a price, or on a percentage change
- Alerts fire in-app via toast notification when triggered
- Quick links to DexScreener, DexTools, and Etherscan for each token
- Multiple tokens tracked simultaneously
Fund Wallets
ENHANCED+Fund multiple wallets at once using SplitNOW — a cross-exchange routing API that delivers funds from CEX or OTC desks, breaking the on-chain link between your source of funds and your wallets.
- Select a source wallet and one or more target wallets with individual ETH amounts
- Pick which exchanger (CEX/OTC desk) to route through per target wallet
- Funds arrive from external exchange wallets — no direct on-chain connection to source
- Live balance tracker: shows allocated amount vs remaining ETH to distribute
- Best-rate discovery: compare exchangers before committing
- Server-side only — SplitNOW API key is never exposed to the browser
EVM Bundler
ENHANCED+Build and submit atomic Flashbots / bloXroute bundles. The primary use case is token launches: include addLiquidityETH and multiple buy transactions in the same block, guaranteed to land in order.
- Compose a bundle: optional setup tx + trigger tx + up to N buy transactions
- Calldata builder for addLiquidityETH (token amount, ETH, slippage, deadline)
- Calldata builder for enableTrading (for tokens with an openTrading mechanism)
- Set a coinbase tip (ETH bribe) to incentivise validators for priority inclusion
- Simulates bundle before submission to catch errors before spending gas
- Submits to bloXroute (which broadcasts to all major builders) for maximum reach
- Supports Ethereum mainnet
Sniper
ENHANCED+The Sniper watches for a token launch and fires your buy bundle atomically with — or immediately after — the liquidity add, depending on the mode.
Mempool Mode
Watches the pending mempool for a specified wallet calling a specific function selector (e.g. addLiquidityETH). When detected, immediately builds an atomic bundle containing the dev's tx and your buy transactions, and submits via bloXroute. Your buys land in the same block, in the same bundle — position 1 is guaranteed relative to public buyers.
Simulation Mode
Simulates a buy on the token contract every block. When the simulation succeeds (token is tradeable), submits your buy bundle immediately. Used when the dev's launch tx is never visible in the public mempool (e.g. private submission or contract-based launch).
- Set trigger wallet address and function selector to watch (mempool mode)
- Configure multiple buy wallets with individual ETH amounts
- Set tip (coinbase bribe) per bundle for priority inclusion
- Private submission via bloXroute — competitors cannot see your intent
- Works with My Contract for contract-based buying
Flash Deployer
ENHANCED+Deploy and launch an ERC-20 token in one click. Flash Deployer handles contract deployment, liquidity addition, and optional bundle buys — all submitted as a private atomic bundle.
Contract Types
Basic ERC-20
A simple, clean ERC-20 token with no special mechanics. Ideal for straightforward launches. Deploy + add liquidity in a single action.
OpenTrading ERC-20
Includes buy/sell taxes, max wallet limit, max transaction limit, and an openTrading() function that enables trading after launch. Owner controls are standard and removable post-launch.
- Set name, symbol, supply, and (optionally) website, Telegram, and Twitter
- Choose liquidity amount (ETH) and initial token allocation to pool
- Optional: add bundle buys at launch — individual wallets or fixed packages
- All transactions (deploy + addLiquidity + buys) submitted as an atomic Flashbots bundle
Post-Launch Panel
- Verify contract source code on Etherscan with one click
- Renounce ownership of the contract
- Remove trading limits (max wallet, max tx)
- Set buy/sell tax to 0%
- Approve and remove liquidity from the Uniswap pool
- Burn LP tokens (send to dead address)
- Lock LP tokens via Unicrypt UniswapV2Locker
Private Node
Every RPC call on Ether.cat is routed through a dedicated private Ethereum full node running Reth — not a shared public endpoint like Infura or Alchemy.
- Dedicated hardware — no rate limits, no throttling, no shared congestion
- Full Ethereum execution client (Reth) + consensus client (Lighthouse)
- Private mempool access — see pending transactions before they are mined
- Faster transaction propagation due to direct node connection
- Private transaction submission via bloXroute to all major builders simultaneously
- Fallback routing: Flashbots relay → MEV Blocker if primary path is unavailable
bloXroute
Submits private transactions to all major block builders simultaneously via the bloXroute relay network. Highest inclusion probability. Your transaction remains invisible in the public mempool until the block is produced.
Flashbots
Used as a secondary relay when bloXroute is unavailable or for explicit bundle submission. Flashbots MEV-Share relay is the industry standard for private bundle submission on Ethereum mainnet.
