Sentio Protocol’s SEN is an ERC-20 token on Ethereum that powers a no-code platform for building and monetizing autonomous on-chain AI agents. If you’re researching SEN using the address 0x421b05cf5ce28cb7347e73e2278e84472f0e4a88, you’re looking at the Ethereum-based Sentio token—not a BNB Chain asset. Sentio’s AI agent platform supports multiple chains (Ethereum, BNB Chain, Polygon, Solana), but this specific SEN contract lives on Ethereum.

What is Sentio Protocol (SEN)?

Sentio Protocol is an AI infra and marketplace that lets anyone—no coding required—create autonomous smart-contract agents that interact with DeFi, NFTs, and other on-chain data. Think drag-and-drop logic for agents that can trade, rebalance, analyze data, or execute automated strategies across ecosystems like Uniswap, Aave, Curve, and PancakeSwap.

SEN is the native token that fuels this marketplace and aligns incentives for creators and users.

• Staking and rewards: Stake SEN to earn rewards and support the network’s health and usage.
• Marketplace payments: Pay for deploying and using AI agents, and for other in-market services.
• Access to resources: Use SEN to access compute and data services offered through the marketplace.

  • Connect a wallet like MetaMask.
  • Paste the SEN contract address to load the correct token.
  • Select your trading pair (e.g., ETH → SEN), review gas and slippage, then swap.

Important clarification: SEN vs. Senspark’s SEN

Multiple projects use the “SEN” ticker. The Sentio Protocol token covered here is on Ethereum:

• Sentio Protocol (Ethereum): 0x421b05cF5Ce28Cb7347E73e2278E84472F0E4A88

A different SEN exists on BNB Chain for Senspark (a GameFi/Metaverse project):

• Senspark (BNB Chain): 0xb43ac9a81eda5a5b36839d5b6fc65606815361b0
• Primary DEX: PancakeSwap
• Note: Senspark’s contract includes mint permissions; review risk accordingly.

Always verify the exact contract on a chain’s official explorer (Etherscan, BscScan, PolygonScan, Solscan) before buying.

Risks and things to watch

• Volatility: SEN has traded far below its all-time high; expect swings.
• Liquidity fragmentation: Liquidity may concentrate on a handful of venues; check pool depth before larger orders.
• Ticker confusion: Multiple “SEN” tokens exist—address verification is non-negotiable.
• Smart-contract risk: While community scanners flag low honeypot risk for the Ethereum contract, you should still evaluate approvals and read contract methods directly on Etherscan.
