 # Project Summary
 
-The goal of SeedSigner is to lower the cost and complexity of Bitcoin multi-signature wallet use. To accomplish this goal, SeedSigner offers anyone the opportunity to build a verifiably air-gapped, stateless Bitcoin signing device using inexpensive, publicly available hardware components (usually < $50). SeedSigner helps users save with Bitcoin by assisting with trustless private key generation and multi-signature wallet setup, and helps users transact with Bitcoin via a secure, air-gapped QR-exchange signing model.

SeedSigner helps users save with Bitcoin by assisting with trustless private key generation and multisignature (aka "multisig") wallet setup, and helps users transact with Bitcoin via a secure, air-gapped QR-exchange signing model.

 ### Feature Highlights:
-* Calculate word 12/24 of a BIP39 seed phrase
-* Create a 24-word BIP39 seed phrase with 99 dice rolls
-* Create a 24-word BIP39 seed phrase by taking a digital photo 
-* Temporarily store up to 3 seed phrases while device is powered
-* Guided interface to manually create a SeedQR for instant input [(demo video here)](https://youtu.be/c1-PqTNx1vc)
-* BIP39 passphrase / word 25 support
-* Native Segwit Multisig XPUB generation w/ QR display
-* Scan and parse transaction data from animated QR codes
+* Calculate the final word (aka checksum) of a 12- or 24-word BIP39 seed phrase
+* Create a 24-word BIP39 seed phrase with 99 dice rolls or a 12-word with 50 rolls [(Verifying dice seed generation)](docs/dice_verification.md)
+* Create a 12- or 24-word BIP39 seed phrase via image entropy from the onboard camera 
+* Temporarily stores seeds in memory while the device is powered; all memory is wiped when power is removed
+* SD card removable after boot to ensure no secret data can be written to it
+* Guided interface to manually transcribe a seed to the SeedQR format for instant seed loading [(demo video here)](https://youtu.be/c1-PqTNx1vc)
+* BIP39 passphrase (aka "word 25") support
+* Native Segwit Multisig XPUB generation
+* PSBT-compliant; scan and parse transaction data from animated QR codes
 * Sign transactions & transfer XPUB data using animated QR codes [(demo video here)](https://youtu.be/LPqvdQ2gSzs)
-* Live preview during photo-to-seed and QR scanning UX
+* Live preview during image entropy seed generation and QR scanning UX
 * Optimized seed word entry interface
 * Support for Bitcoin Mainnet & Testnet
 * Support for custom user-defined derivation paths
 * On-demand receive address verification
+* Address Explorer for single sig and multisig wallets
 * User-configurable QR code display density
 * Responsive, event-driven user interface

 ### Planned Upcoming Improvements / Functionality:
-* Single-sig and multi-sig change address verification
-* Re-imagined, graphically-focused user interface
 * Multi-language support
-* Customized Linux live-boot OS to allow MicroSD card removal
+* Port to MicroPython to broaden the range of compatible hardware to include low-cost microcontrollers
 * Other optimizations based on user feedback!
