inlayr

A modular, chain‑agnostic SDK for building and integrating crypto quoting and trading flows on DEXs.

Status: Experimental (v0.2.1). 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

Installation

The base install:

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

import inlayr
print (inlayr.__version__)

High‑level sketch (pseudocode)

# 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 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:

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.
