Steyble is the all-in-one self-custodial crypto super app. It bundles DEX aggregation, liquid staking, perpetuals, prediction markets, copy trading, P2P, a crypto Visa card, and a cross-chain bridge into a single mobile and web app.

Is Steyble self-custodial?

Yes. Steyble never holds your funds. You connect your own wallet (or use Steyble's built-in self-custodial wallet) and sign every transaction yourself. Steyble is the interface; the smart contracts and your keys do the work.

Where is Steyble available?

Steyble is available globally on web and mobile (iOS and Android) with region-specific guides for Dubai, the UK, and Singapore. Some specific products may be restricted in certain jurisdictions for regulatory reasons.

How much does Steyble cost?

The Steyble app is free to download and use. We earn revenue from small fees on swaps, perps trading, and the crypto card — fully disclosed before each transaction. Staking, prediction markets, and copy trading have no Steyble fee on top of the underlying protocol fee.

What is a DeFi aggregator?

A DeFi aggregator is a platform that routes your crypto swaps across hundreds of decentralised exchanges (DEXes) simultaneously to find the best rate and lowest slippage. Instead of trading on a single DEX like Uniswap, an aggregator like Steyble splits your trade across multiple pools and chains to maximise your output.

What is a crypto super app?

A crypto super app is a single non-custodial platform that combines every DeFi service — token swapping, staking, perpetuals trading, prediction markets, copy trading, cross-chain bridging, and crypto cards — in one interface. Steyble is a crypto super app, meaning you never need to switch between multiple DeFi applications.

Is Steyble self-custodial?

Yes. Steyble is entirely non-custodial and self-custodial. You hold your private keys at all times. Steyble provides the interface and smart contract routing, but never holds, controls, or has access to your assets. Every transaction requires your explicit wallet signature.

How do prediction markets work in crypto?

Crypto prediction markets let you buy or sell shares in the outcome of real-world events using on-chain smart contracts. If you buy a 'Yes' share at $0.35, you receive $1 if the event occurs (a $0.65 profit) or lose $0.35 if it does not. Markets cover crypto prices, elections, sports results, and macro events. Steyble's prediction markets are non-custodial — your funds remain in your wallet until settlement.

What are perpetual futures in crypto?

Perpetual futures (perps) are leveraged crypto trading contracts with no expiry date. Unlike traditional futures that expire monthly, perps let you hold long or short positions indefinitely. A periodic funding rate keeps the perp price aligned with spot. Steyble perpetuals run on decentralised smart contracts — you trade directly from your own wallet with full transparency into liquidation parameters.

How does copy trading work on Steyble?

Copy trading on Steyble automatically mirrors the on-chain trades of verified top-performing wallet strategies. You choose the wallets you want to copy, set your position sizing and risk limits, and Steyble replicates their trades in real time. Unlike centralised copy trading, Steyble is non-custodial — you never give up control of your funds.

What is the best way to earn passive income with crypto in 2026?

The best methods for passive crypto income in 2026 are: (1) liquid staking ETH or SOL at 3.5–8% APY, (2) lending stablecoins on lending protocols at 5–9% APY, (3) non-custodial copy trading to mirror proven wallet strategies, (4) providing liquidity to stablecoin pools at 3–6% APY, and (5) on-chain prediction markets for event-driven returns. Steyble provides access to all five methods in a single platform.

What is the best DEX aggregator in 2026?

The best DEX aggregators in 2026 route across 15+ blockchains and 100+ liquidity sources with MEV protection. Steyble's swap aggregator covers 250+ liquidity sources across Ethereum, Solana, Arbitrum, Base, and more — consistently delivering better rates than going directly to any single DEX. For large swaps, using an aggregator saves 0.5–2% per transaction.

AI Agents Using Crypto: The MCP + On-Chain Wallet Stack in 2026

An AI agent that holds value, pays for resources, and trades on-chain needs a specific stack: a wallet, an MCP server, a policy layer, and a settlement chain.

The most consequential shift in crypto since the launch of the smart-contract is happening quietly in 2026: AI agents are starting to hold their own wallets, pay for their own resources, and execute on-chain transactions on behalf of their users. The technical stack that makes this work — wallet abstraction, the Model Context Protocol (MCP), a policy layer, and a low-fee settlement chain — is finally legible enough to describe end-to-end.

Why an AI Agent Needs a Wallet at All

To pay for compute: GPU time on Akash, Render, or Vast.ai sells per-second in stablecoins
To pay for inference: pay-per-call APIs for niche models settle in USDC on the agent's behalf
To pay for data: real-time data feeds (financial, weather, sports) increasingly accept stablecoin micropayments
To execute decisions on the user's behalf: an agent that recommends a swap can also execute it, end-to-end
To accumulate revenue: an agent that performs paid work (research, trading, content) can be paid directly to its wallet

The MCP Layer

Model Context Protocol (MCP) is the now-dominant protocol for letting an LLM call external tools — wallet operations, swap quotes, on-chain reads, off-chain APIs — through a standardised JSON-RPC interface. A wallet exposed as an MCP server lets any MCP-compatible LLM (Claude, GPT, Gemini, Llama-derived agents) propose and authorise transactions through the agent's reasoning loop, rather than via brittle shell-out scripts. MCP is the missing protocol-layer that makes 'AI agents on-chain' practical instead of aspirational.

The Policy Layer (Critical)

Per-transaction limits: 'never authorise more than $50 in a single tx without human approval'
Daily aggregate limits: 'never spend more than $200/day from this wallet'
Allow-list of contracts: 'only swap on Uniswap, Curve, or the Steyble router'
Allow-list of tokens: 'never swap into a token launched in the last 90 days'
Time-of-day restrictions, kill-switch, and human-in-the-loop hooks on every threshold breach

The Settlement Chain

Agents make many small, fast transactions — closer to micropayments than to investor-grade transfers. The right settlement chain has sub-cent gas, sub-second finality, and a healthy ERC-4337 ecosystem. Base, Solana, Arbitrum, and the new wave of agent-focused L2s (Stoa, Cellium) are converging on this profile. Ethereum mainnet remains the right choice for high-value treasury transfers; the hot path for agent activity is L2 or Solana.

The Steyble Agent Surface

Steyble's wallet is being exposed as an MCP server in 2026, with a built-in policy layer (per-tx limits, allow-lists, kill-switches) and one-click derivation of an agent sub-account. The result is that any MCP-compatible LLM can be granted bounded transaction authority over a Steyble wallet without compromising the user's primary keys — the canonical 2026 architecture for AI agents that need to actually move value.
