# inlayr
_A modular, chain‑agnostic SDK for building and integrating crypto quoting and trading flows on DEXs._
> **Status:** Experimental (v0.1.21). APIs may change before 1.0.

---
inlayr aims to provide a clean, typed interface for **quoting, routing and submitting swaps** across multiple chains.
- ✅ **Pluggable backends** — add providers without touching the core
- ✅ **No commission** — avoid wallet-level commissions
- ✅ **Integration** — build your own DEX trading bots
If you just want the docs: jump to **[Quickstart](#quickstart)** or **[Installation](#installation)**.
---
## Installation
The base install:
```bash
pip install inlayr
```
Supported Python: **3.9+**
## Quickstart
> The exact API surface may evolve before 1.0. The snippets below show the intended usage patterns while staying dependency‑light.
### Verify install
```python
import inlayr
print (inlayr.__version__)
```
### High‑level sketch (pseudocode)
```python
# Illustrative only. Actual class and method names may differ in your version.
# 1) Import provider interface
from inlayr.provider import get_provider
# 2) Fetch your private key
solana_pk = open(r"solana_pk").read()
# 3) Configure Chain, RPC, and Aggregator
provider = get_provider(
chain = "solana",
chain_params = {"wallet_pk": solana_pk},
rpc = "solana",
rpc_params = {"chain_id": None},
aggregator = "jupiter",
aggregator_params = {}
)
# 4) Perform operations (e.g. request a quote)
quote = provider.get_quote(
source_token = "4eDf52YYzL6i6gbZ6FXqrLUPXbtP61f1gPSFM66M4XHe",
source_amount = 1_000_000_000,
destination_token = "So11111111111111111111111111111111111111112",
slippage = 1_000
)
```
Please refer to [examples](https://github.com/OlegMitsik/inlayr/tree/main/examples) for more functional use cases.
## Configuration
Common runtime knobs (RPC endpoints, routing preferences, etc) are typically supplied by you at construction time.
Currently supported configurations:
- **RPCs** — ankr, 1rpc, solana
- **Chains** — evm, solana
- **Aggregators** — 0x, 1inch, jupiter, raydium
## Security
Private keys are provided only at runtime. They are never logged, transmitted, or stored by us.
## Type hints
- The package includes `py.typed` so type checkers (mypy, pyright) understand the public API.
- We aim to keep public call signatures stable across minor versions; experimental pieces will be marked in docstrings where applicable.
## Contributing
PRs and issues are welcome! A few guidelines:
- Discuss larger changes in an issue first.
- Ensure `python -m build && twine check dist/*` succeeds.
- Add or update tests (`pytest`).
To run tests:
```bash
pip install -e '.[test]'
pytest -q
```
## Versioning
We use **Semantic Versioning**. Until `1.0.0`, minor bumps may include small breaking changes as we refine the API.
