🎯 PumpFun Trading Example (Encrypted Keystore)

Same trading flow as pumpfun_trade, but the wallet uses a sol-safekey file or fallback KEYPAIR_BASE58.

When to use

Token must still be on PumpFun (not graduated); use pumpswap_trade_with_safekey after migration.
Set keystore_path in config/*/solana.yaml (e.g. ./keystore.json), enter the password at runtime or set KEYSTORE_PASSWORD.
If keystore_path is empty, KEYPAIR_BASE58 is accepted as a fallback (less secure).

cd sol-safekey
cargo run --release -- export <private_key_or_mnemonic> ../pumpfun_trade_with_safekey/keystore.json

Then point keystore_path in pumpfun_trade_with_safekey/config/dev/solana.yaml to that file.

For longer documentation (SWQoS, nonce, security), see pumpswap_trade_with_safekey/README.md—same layout, different protocol (PumpSwap).

Clone sol-safekey separately and export keystore.json (this repo does not vendor it)—see root README.md.
In this crate:

cp .env.example .env
cp config/dev/solana.yaml.example config/dev/solana.yaml
cp config/dev/trading.yaml.example config/dev/trading.yaml

Edit YAML/keystore_path, SWQoS, nonce. Do not commit .env or filled YAML.

cd pumpfun_trade_with_safekey
./run.sh <MINT_ADDRESS>

cargo build --release
# Binary: build-cache/release/pumpfun_trade_with_safekey
./build-linux-release.sh

1 round by default: buy → wait ~30s → sell full mint balance (ROUNDS in src/run.rs).
2+ SWQoS requires durable nonce; empty YAML placeholders are skipped so NONCE_ACCOUNT still works.
Params are refreshed from RPC before sell, same as pumpfun_trade.
