## Sections

## Articles

- [Slippage on Solana explained](https://www.solspread.net/slippage-on-solana-explained/): decomposes realised slippage into fee, price impact and timing components, with the closed form impact = in / (x + in) for constant-product pools.
- [Spread vs slippage vs price impact](https://www.solspread.net/spread-vs-slippage-vs-price-impact/): distinguishes the three terms, where each is visible in a swap interface, and which of them a trader controls.
- [Setting slippage tolerance](https://www.solspread.net/setting-slippage-tolerance/): what the tolerance value does at the instruction level and how depth and urgency change the right band.
- [Quote vs fill](https://www.solspread.net/quote-vs-fill/): the lifecycle of a quote, where it goes stale, and a symptom-to-cause diagnostic table for bad fills.
- [Route splitting and price impact](https://www.solspread.net/route-splitting-and-price-impact/): why splitting an order across pools lowers impact, and when an extra leg makes the fill worse.
- [Aggregators vs direct pool swaps](https://www.solspread.net/aggregators-vs-direct-pool-swaps/): when a direct pool swap beats aggregation, with a comparison table and a decision checklist.
- [Sandwich risk on Solana](https://www.solspread.net/sandwich-risk-on-solana/): how the pattern works in a leader-based environment, what makes an order attractive, and graded mitigations.
- [Trade sizing and pool depth](https://www.solspread.net/trade-sizing-and-depth/): sizing orders as a percentage of pool reserves, splitting over time versus over routes.
- [Execution cost breakdown](https://www.solspread.net/execution-cost-breakdown/): network fee, priority fee, pool fee, spread, impact and failed attempts summed in one illustrative example.
- [Measuring execution quality](https://www.solspread.net/measuring-execution-quality/): benchmark choice, computing realised slippage from transaction data, landing rate and controlled path comparison.
