To revoke is the act of resetting a token allowance to zero (or a lower amount) via an on-chain transaction, permanently removing a smart contract’s permission to transfer the specified tokens from your wallet.
Risk-Reward Ratio (R:R)
The risk-reward ratio compares potential loss to potential profit in a trade.
Roadmap

Runes (Bitcoin)
Runes is a fungible token protocol on Bitcoin, designed as a more efficient alternative to BRC-20. It uses Bitcoin's native UTXO model to track token balances directly, without requiring inscriptions or off-chain indexers to interpret JSON.

Self Custody
Self-custody (or self-custodial ownership) means you alone control the private keys to your cryptocurrency, with no exchange, bank, or third party holding them on your behalf.
Shared Sequencer
A shared sequencer is a decentralized network of nodes that orders transactions on behalf of multiple Layer 2 rollups simultaneously. Rather than each rollup running its own centralized sequencer, they share an external ordering layer to enable cross-rollup composability and resist censorship.
Slashing
Slashing is a penalty applied to validators who break network rules or behave incorrectly.
Slippage
Slippage is the difference between the expected price of a trade at the time of submission and the actual executed price, caused by market movement or insufficient liquidity during confirmation.
Smart Contract
A smart contract is self-executing code stored on a blockchain that automatically performs actions when certain conditions are met.
Sniping Bot
A sniping bot is automated software that monitors blockchains or mempools for specific events — new token launches, liquidity additions, price thresholds — and submits transactions to act on them faster than a human could, often within the same block.
